reallocf -- general purpose memory allocation functions
Utility functions from BSD systems (libbsd, -lbsd)
reallocf(void *ptr, size_t size);
The reallocf() function changes the size of the previously allocated memory referenced by ptr to size bytes. The contents of the memory are
unchanged up to the lesser of the new and old sizes. If the new size is larger, the contents of the newly allocated portion of the memory
are undefined. Upon success, the memory referenced by ptr is freed and a pointer to the newly allocated memory is returned. Note that
reallocf() may move the memory allocation, resulting in a different return value than ptr. If ptr is NULL, the reallocf() function behaves
identically to malloc() for the specified size. Upon failure, when the requested memory cannot be allocated, the passed pointer is freed to
ease the problems with traditional coding styles for reallocf() causing memory leaks in libraries.
The reallocf() function returns a pointer, possibly identical to ptr, to the allocated memory if successful; otherwise a NULL pointer is
returned, and errno is set to ENOMEM if the error was the result of an allocation failure. The buffer is deallocated in this case.
SEE ALSO brk(2), mmap(2), alloca(3), calloc(3), free(3), malloc(3), posix_memalign(3), realloc(3),
The reallocf() function first appeared in FreeBSD 3.0.
