NAME

memccpy - copy memory area

Standard C library (libc, -lc)

bash

#include <string.h>

bash

void *memccpy(void \ndest\n[restrict .\nn\n], const void \nsrc\n[restrict .\nn\n],\n
\n              int \nc\n, size_t \nn\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).
