MEMCCPY(3) FreeBSD Library Functions Manual MEMCCPY(3) NAME memccpy - copy string until character found LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <string.h> void * memccpy(void * restrict dst, const void * restrict 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. If src and dst overlap, behavior is undefined. SEE ALSO bcopy(3), memcpy(3), memmove(3), strcpy(3) STANDARDS The memccpy() function conforms to IEEE Std 1003.1-2004 ("POSIX.1") and ISO/IEC 9899:2024 ("ISO C23"). HISTORY The memccpy() function first appeared in 4.4BSD and was first specified in the System V Interface Definition, First Edition ("SVID1"). The restrict keyword was added to the prototype in FreeBSD 5.0.0 in accordance with the updated specification of IEEE Std 1003.1-2004 ("POSIX.1").
