Upon successful completion with both nelem and elsize non-zero, calloc() shall return a pointer to the allocated space. If either nelem or elsize is 0, then either: * A null pointer shall be returned and errno may be set to an implementation-defined value, or * A pointer to the allocated space shall be returned.
The calloc () function allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. The memory is set to zero. If nmemb or size is 0, then calloc () returns either NULL, or a unique pointer value that can later be successfully passed to free ().
The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME. calloc — a memory allocator. SYNOPSIS #include <stdlib.h> void *calloc(size_t nelem, size_t elsize); DESCRIPTION
