If the space is available, -<> returns a pointer to a newly allocated block as its result. - -If you already have a block of storage allocated by <>, but -you no longer need all the space allocated to it, you can make it -smaller by calling <> with both the object pointer and the -new desired size as arguments. <> guarantees that the -contents of the smaller object match the beginning of the original object. - -Similarly, if you need more space for an object, use <> to -request the larger size; again, <> guarantees that the -beginning of the new, larger object matches the contents of the -original object. - -When you no longer need an object originally allocated by <> -or <> (or the related function <>), return it to the -memory storage pool by calling <> with the address of the object -as the argument. You can also use <> for this purpose by -calling it with <<0>> as the <[nbytes]> argument. - -The <> function returns a block of size <[nbytes]> aligned -to a <[align]> boundary. The <[align]> argument must be a power of -two. - -The <> function takes a pointer to a block -allocated by <>. It returns the amount of space that is -available in the block. This may or may not be more than the size -requested from <>, due to alignment or minimum size -constraints. - -The alternate functions <<_malloc_r>>, <<_realloc_r>>, <<_free_r>>, -<<_memalign_r>>, and <<_malloc_usable_size_r>> are reentrant versions. -The extra argument <[reent]> is a pointer to a reentrancy structure. - -If you have multiple threads of execution which may call any of these -routines, or if any of these routines may be called reentrantly, then -you must provide implementations of the <<__malloc_lock>> and -<<__malloc_unlock>> functions for your system. See the documentation -for those functions. - -These functions operate by calling the function <<_sbrk_r>> or -<>, which allocates space. You may need to provide one of these -functions for your system. <<_sbrk_r>> is called with a positive -value to allocate more space, and with a negative value to release -previously allocated space if it is no longer required. -@xref{Stubs}. - -RETURNS -<> returns a pointer to the newly allocated space, if -successful; otherwise it returns <>. If your application needs -to generate empty objects, you may use <> for this purpose. - -<> returns a pointer to the new block of memory, or <> -if a new block could not be allocated. <> is also the result -when you use `<,0)>>' (which has the same effect as -`<)>>'). You should always check the result of -<>; successful reallocation is not guaranteed even when -you request a smaller object. - -<> does not return a result. - -<> returns a pointer to the newly allocated space. - -<> returns the usable size. - -PORTABILITY -<>, <>, and <> are specified by the ANSI C -standard, but other conforming implementations of <> may -behave differently when <[nbytes]> is zero. - -<> is part of SVR4. - -<> is not portable. - -Supporting OS subroutines required: <>. */ - -#include <_ansi.h> -#include -#include -#include - -#ifndef _REENT_ONLY - -_PTR -_DEFUN (malloc, (nbytes), - size_t nbytes) /* get a block */ -{ - return _malloc_r (_REENT, nbytes); -} - -void -_DEFUN (free, (aptr), - _PTR aptr) -{ - _free_r (_REENT, aptr); -} - -#endif - -#endif /* ! defined (MALLOC_PROVIDED) */ -- cgit v1.2.3
