NAME
memccpy - memory unti-an-includin-character copy
LIBRARY
Standard C library
( libc,~ -lc)
SYNOPSIS
#include~<string.h> // see memory.h(3head)
void *memccpy(size_t n;
void dest[restrict n], const void src[restrict n],
int c, size_t n);
DESCRIPTION
The
memccpy()
function copies no more than
n
bytes from
memory area
src
to memory area
dest,
stopping when the
character
c
is found
( c
is copied).
If the memory areas overlap, the results are undefined.
RETURN VALUE
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.

HISTORY
POSIX.-2001, SVr4, 4.3BSD.
CAVEATS
This function has recently (since C23)
started being misused for copying strings with truncation.
That's not its intended use,
and is most likely to result in bugs if used for that.
This function was designed for
the quite different (and niche) task of implementing
fgets(3).
