memccpy — copy bytes in memory

#include <string.h>

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

The memccpy() function copies 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 behaviour is undefined.

The memccpy() function returns 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 .

No errors are defined.

None.

The memccpy() function does not check for the overflow of the receiving memory area.

None.
