It is -called a macro processor because it allows you to define \c -.I macros\c -\&, -which are brief abbreviations for longer constructs. - -The C preprocessor provides four separate facilities that you can use as -you see fit: -.TP -\(bu -Inclusion of header files. These are files of declarations that can be -substituted into your program. -.TP -\(bu -Macro expansion. You can define \c -.I macros\c -\&, which are abbreviations -for arbitrary fragments of C code, and then the C preprocessor will -replace the macros with their definitions throughout the program. -.TP -\(bu -Conditional compilation. Using special preprocessing directives, you -can include or exclude parts of the program according to various -conditions. -.TP -\(bu -Line control. If you use a program to combine or rearrange source files into -an intermediate file which is then compiled, you can use line control -to inform the compiler of where each source line originally came from. -.PP -C preprocessors vary in some details. For a full explanation of the -GNU C preprocessor, see the -.B info -file `\|\c -.B cpp.info\c -\&\|', or the manual -.I The C Preprocessor\c -\&. Both of these are built from the same documentation source file, `\|\c -.B cpp.texinfo\c -\&\|'. The GNU C -preprocessor provides a superset of the features of ANSI Standard C. - -ANSI Standard C requires the rejection of many harmless constructs commonly -used by today's C programs. Such incompatibility would be inconvenient for -users, so the GNU C preprocessor is configured to accept these constructs -by default. Strictly speaking, to get ANSI Standard C, you must use the -options `\|\c -.B \-trigraphs\c -\&\|', `\|\c -.B \-undef\c -\&\|' and `\|\c -.B \-pedantic\c -\&\|', but in -practice the consequences of having strict ANSI Standard C make it -undesirable to do this. - -Most often when you use the C preprocessor you will not have to invoke it -explicitly: the C compiler will do so automatically. However, the -preprocessor is sometimes useful individually. - -When you call the preprocessor individually, either name -(\c -.B cpp\c -\& or \c -.B cccp\c -\&) will do\(em\&they are completely synonymous. - -The C preprocessor expects two file names as arguments, \c -.I infile\c -\& and -\c -.I outfile\c -\&. The preprocessor reads \c -.I infile\c -\& together with any other -files it specifies with `\|\c -.B #include\c -\&\|'. All the output generated by the -combined input files is written in \c -.I outfile\c -\&. - -Either \c -.I infile\c -\& or \c -.I outfile\c -\& may be `\|\c -.B \-\c -\&\|', which as \c -.I infile\c -\& -means to read from standard input and as \c -.I outfile\c -\& means to write to -standard output. Also, if \c -.I outfile\c -\& or both file names are omitted, -the standard output and standard input are used for the omitted file names. -.SH OPTIONS -Here is a table of command options accepted by the C preprocessor. -These options can also be given when compiling a C program; they are -passed along automatically to the preprocessor when it is invoked by -the compiler. -.TP -.B \-P -Inhibit generation of `\|\c -.B #\c -\&\|'-lines with line-number information in -the output from the preprocessor. This might be -useful when running the preprocessor on something that is not C code -and will be sent to a program which might be confused by the -`\|\c -.B #\c -\&\|'-lines. -.TP -.B \-C -Do not discard comments: pass them through to the output file. -Comments appearing in arguments of a macro call will be copied to the -output before the expansion of the macro call. -.TP -.B \-traditional -Try to imitate the behavior of old-fashioned C, as opposed to ANSI C. -.TP -.B \-trigraphs -Process ANSI standard trigraph sequences. These are three-character -sequences, all starting with `\|\c -.B ??\c -\&\|', that are defined by ANSI C to -stand for single characters. For example, `\|\c -.B ??/\c -\&\|' stands for -`\|\c -.BR "\e" "\|'," -so `\|\c -.B '??/n'\c -\&\|' is a character constant for a newline. -Strictly speaking, the GNU C preprocessor does not support all -programs in ANSI Standard C unless `\|\c -.B \-trigraphs\c -\&\|' is used, but if -you ever notice the difference it will be with relief. - -You don't want to know any more about trigraphs. -.TP -.B \-pedantic -Issue warnings required by the ANSI C standard in certain cases such -as when text other than a comment follows `\|\c -.B #else\c -\&\|' or `\|\c -.B #endif\c -\&\|'. -.TP -.B \-pedantic\-errors -Like `\|\c -.B \-pedantic\c -\&\|', except that errors are produced rather than -warnings. -.TP -.B \-Wtrigraphs -Warn if any trigraphs are encountered (assuming they are enabled). -.TP -.B \-Wcomment -.TP -.B \-Wcomments -Warn whenever a comment-start sequence `\|\c -.B /*\c -\&\|' appears in a comment. -(Both forms have the same effect). -.TP -.B \-Wall -Requests both `\|\c -.B \-Wtrigraphs\c -\&\|' and `\|\c -.B \-Wcomment\c -\&\|' (but not -`\|\c -.B \-Wtraditional\c -\&\|'). -.TP -.B \-Wtraditional -Warn about certain constructs that behave differently in traditional and -ANSI C. -.TP -.BI "\-I " directory\c -\& -Add the directory \c -.I directory\c -\& to the end of the list of -directories to be searched for header files. -This can be used to override a system header file, substituting your -own version, since these directories are searched before the system -header file directories. If you use more than one `\|\c -.B \-I\c -\&\|' option, -the directories are scanned in left-to-right order; the standard -system directories come after. -.TP -.B \-I\- -Any directories specified with `\|\c -.B \-I\c -\&\|' options before the `\|\c -.B \-I\-\c -\&\|' -option are searched only for the case of `\|\c -.B #include "\c -.I file\c -\&"\c -\&\|'; -they are not searched for `\|\c -.B #include <\c -.I file\c -\&>\c -\&\|'. - -If additional directories are specified with `\|\c -.B \-I\c -\&\|' options after -the `\|\c -.B \-I\-\c -\&\|', these directories are searched for all `\|\c -.B #include\c -\&\|' -directives. - -In addition, the `\|\c -.B \-I\-\c -\&\|' option inhibits the use of the current -directory as the first search directory for `\|\c -.B #include "\c -.I file\c -\&"\c -\&\|'. -Therefore, the current directory is searched only if it is requested -explicitly with `\|\c -.B \-I.\c -\&\|'. Specifying both `\|\c -.B \-I\-\c -\&\|' and `\|\c -.B \-I.\c -\&\|' -allows you to control precisely which directories are searched before -the current one and which are searched after. -.TP -.B \-nostdinc -Do not search the standard system directories for header files. -Only the directories you have specified with `\|\c -.B \-I\c -\&\|' options -(and the current directory, if appropriate) are searched. -.TP -.B \-nostdinc++ -Do not search for header files in the C++ specific standard -directories, but do still search the other standard directories. -(This option is used when building libg++.) -.TP -.BI "\-D " "name"\c -\& -Predefine \c -.I name\c -\& as a macro, with definition `\|\c -.B 1\c -\&\|'. -.TP -.BI "\-D " "name" = definition -\& -Predefine \c -.I name\c -\& as a macro, with definition \c -.I definition\c -\&. -There are no restrictions on the contents of \c -.I definition\c -\&, but if -you are invoking the preprocessor from a shell or shell-like program -you may need to use the shell's quoting syntax to protect characters -such as spaces that have a meaning in the shell syntax. If you use more than -one `\|\c -.B \-D\c -\&\|' for the same -.I name\c -\&, the rightmost definition takes effect. -.TP -.BI "\-U " "name"\c -\& -Do not predefine \c -.I name\c -\&. If both `\|\c -.B \-U\c -\&\|' and `\|\c -.B \-D\c -\&\|' are -specified for one name, the `\|\c -.B \-U\c -\&\|' beats the `\|\c -.B \-D\c -\&\|' and the name -is not predefined. -.TP -.B \-undef -Do not predefine any nonstandard macros. -.TP -.BI "\-A " "name(" value ) -Assert (in the same way as the \c -.B #assert\c -\& directive) -the predicate \c -.I name\c -\& with tokenlist \c -.I value\c -\&. Remember to escape or quote the parentheses on -shell command lines. - -You can use `\|\c -.B \-A-\c -\&\|' to disable all predefined assertions; it also -undefines all predefined macros. -.TP -.B \-dM -Instead of outputting the result of preprocessing, output a list of -`\|\c -.B #define\c -\&\|' directives for all the macros defined during the -execution of the preprocessor, including predefined macros. This gives -you a way of finding out what is predefined in your version of the -preprocessor; assuming you have no file `\|\c -.B foo.h\c -\&\|', the command -.sp -.br -touch\ foo.h;\ cpp\ \-dM\ foo.h -.br -.sp -will show the values of any predefined macros. -.TP -.B \-dD -Like `\|\c -.B \-dM\c -\&\|' except in two respects: it does \c -.I not\c -\& include the -predefined macros, and it outputs \c -.I both\c -\& the `\|\c -.B #define\c -\&\|' -directives and the result of preprocessing. Both kinds of output go to -the standard output file. -.PP -.TP -.BR \-M\ [ \-MG ] -Instead of outputting the result of preprocessing, output a rule -suitable for \c -.B make\c -\& describing the dependencies of the main -source file. The preprocessor outputs one \c -.B make\c -\& rule containing -the object file name for that source file, a colon, and the names of -all the included files. If there are many included files then the -rule is split into several lines using `\|\c -.B \\\\\c -\&\|'-newline. - -`\|\c -.B \-MG\c -\&\|' says to treat missing header files as generated files and assume \c -they live in the same directory as the source file. It must be specified \c -in addition to `\|\c -.B \-M\c -\&\|'. - -This feature is used in automatic updating of makefiles. -.TP -.BR \-MM\ [ \-MG ] -Like `\|\c -.B \-M\c -\&\|' but mention only the files included with `\|\c -.B #include -"\c -.I file\c -\&"\c -\&\|'.
