MEMCCPY(3) Library Functions Manual MEMCCPY(3)

memccpy — copy string until character found

Standard C Library (libc, -lc)

#include <string.h>

void *
memccpy(void *restrict dst, const void *restrict src, int c, size_t n);

The () function copies bytes from string src to string dst. If the character c (as converted to an unsigned char) occurs in the string src, the copy stops and a pointer to the byte after the copy of c in the string dst is returned. Otherwise, n bytes are copied, and a NULL pointer is returned.

The source and destination strings should not overlap, as the behavior is undefined.

The memccpy() function first appeared in 4.4BSD.
