These functions allocate and free memory for the calling process. They are described in the individual manual pages. The memory allocators used in the kernel are described in memoryallocators(9). SEE ALSO
alloca(3), calloc(3), free(3), malloc(3), realloc(3) STANDARDS
These functions, with the exception of alloca() conform to ANSI X3.159-1989 (``ANSI C89''). BSD

alloca, calloc, free, malloc, mmap, realloc -- general memory allocation operations LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <stdlib.h> void * alloca(size_t size); void * calloc(size_t nelem, size_t elsize); void free(void *ptr); void * malloc(size_t size); void * realloc(void *ptr, size_t size); #include <sys/mman.h> void * mmap(void * addr, size_t len, int prot, int flags, int fildes, off_t off); DESCRIPTION
These functions allocate and free memory for the calling process. They are described in the individual manual pages. LEGACY SYNOPSIS
#include <sys/types.h> #include <sys/mman.h> void * mmap(void * addr, size_t len, int prot, int flags, int fildes, off_t off); The include file <sys/types.h> is needed for this function. COMPATIBILITY
mmap() now returns with errno set to EINVAL in places that historically succeeded. The rules have changed as follows: o The flags parameter must specify either MAP_PRIVATE or MAP_SHARED. o The size parameter must not be 0. o The off parameter must be a multiple of pagesize, as returned by sysconf(). SEE ALSO
mmap(2), alloca(3), calloc(3), free(3), malloc(3), realloc(3), compat(5) STANDARDS
These functions, with the exception of alloca() and mmap() conform to ISO/IEC 9899:1990 (``ISO C90''). BSD
