MALLOC(3) Library Functions Manual MALLOC(3) NAME reallocf -- memory reallocation function LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <stdlib.h> void * reallocf(void *ptr, size_t size); DESCRIPTION The reallocf() function is identical to the realloc() function, except that it will free the passed pointer when the requested memory cannot be allo- cated. This is a FreeBSD specific API designed to ease the problems with traditional coding styles for realloc() causing memory leaks in libraries. RETURN VALUES 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 reallocf() function deletes the original buffer when an error occurs. SEE ALSO realloc(3) HISTORY The reallocf() function first appeared in FreeBSD 3.0. FreeBSD 15.1 January 31, 2010 MALLOC(3)
