Library Functions Manual
NAME memccpy — copy string until character found
LIBRARY Standard C Library (libc, -lc)
SYNOPSIS #include <string.h>
memccpy(void *dst, const void *src, int c, size_t len);
DESCRIPTION The memccpy() 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, len bytes are copied, and a null pointer is returned.
HISTORY The memccpy() function first appeared in 4.4BSD.
