3.28 calloc

Function

Allocate and clear memory.

Header

stdlib.h

Declaration

void* __fastcall__ calloc (size_t n, size_t size);

Description

calloc allocates memory for an array of n elements of size size, clears the whole block with binary zeroes and returns a pointer to it. On error (not enough memory available), calloc returns NULL.

Limits

• Clearing the memory may not have the expected effect on all platforms: pointers in the block may not be NULL and floating point variables may not be zero (0.0). In other words: The "clearing" effect of this function should be used with care for portable programs.
• The function is only available as fastcall function, so it may only be used in presence of a prototype.
