+FUNCTION
+<<getc>>---read a character (macro)
+
+INDEX
+	getc
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	int getc(FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	int getc(<[fp]>)
+	FILE *<[fp]>;
+
+DESCRIPTION
+<<getc>> is a macro, defined in <<stdio.h>>.  You can use <<getc>>
+to get the next single character from the file or stream
+identified by <[fp]>.  As a side effect, <<getc>> advances the file's
+current position indicator.
+
+For a subroutine version of this macro, see <<fgetc>>.
+
+RETURNS
+The next character (read as an <<unsigned char>>, and cast to
+<<int>>), unless there is no more data, or the host system reports a
+read error; in either of these situations, <<getc>> returns <<EOF>>.
+
+You can distinguish the two situations that cause an <<EOF>> result by
+using the <<ferror>> and <<feof>> functions.
+
+PORTABILITY
+ANSI C requires <<getc>>; it suggests, but does not require, that
+<<getc>> be implemented as a macro.  The standard explicitly permits
+macro implementations of <<getc>> to use the argument more than once;
+therefore, in a portable program, you should not use an expression
+with side effects as the <<getc>> argument.
+
+Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
+<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
