FUNCTION
<<memccpy>>---copy memory regions with end-token check
ANSI_SYNOPSIS
#include <string.h>
void* memccpy(void *<[out]>, const void *<[in]>,

TRAD_SYNOPSIS
void *memccpy(<[out]>, <[in]>, <[endchar]>, <[n]>
void *<[out]>;
void *<[in]>;
int <[endchar]>;
size_t <[n]>;
DESCRIPTION
This function copies up to <[n]> bytes from the memory region
pointed to by <[in]> to the memory region pointed to by
<[out]>. If a byte matching the <[endchar]> is encountered,
the byte is copied and copying stops.
If the regions overlap, the behavior is undefined.
RETURNS
<<memccpy>> returns a pointer to the first byte following the
<[endchar]> in the <[out]> region. If no byte matching
<[endchar]> was copied, then <<NULL>> is returned.
PORTABILITY
<<memccpy>> is a GNU extension.
<<memccpy>> requires no supporting OS subroutines.
