MEMCCPY(3) Linux Programmer's Manual MEMCCPY(3)

memccpy - copy memory area

#include <string.h>
void *memccpy(void *dest, const void *src, int c, size_t n);

The memccpy() function copies no more than n bytes from memory area src to memory area dest, stopping when the character c is found.
If the memory areas overlap, the results are undefined.

The memccpy() function returns a pointer to the next character in dest after c, or NULL if c was not found in the first n characters of src.

For an explanation of the terms used in this section, see attributes(7).
