MEMCCPY(3) Library Functions Manual MEMCCPY(3)

NAME

memccpy — copy bytes in memory

SYNOPSIS

[XSI]
#include <string.h>

void *memccpy(void *restrict s1, const void *restrict s2,
       int c, size_t n);

DESCRIPTION

The memccpy () function shall copy bytes from memory area s2 into s1, stopping after the first occurrence of byte c (converted to an unsigned char) is copied, or after n bytes are copied, whichever comes first. If copying takes place between objects that overlap, the behavior is undefined.

RETURN VALUE

The memccpy () function shall return a pointer to the byte after the copy of c in s1, or a null pointer if c was not found in the first n bytes of s2.
