NAME
memccpy — copy
bytes in memory
SYNOPSIS
void *memccpy(void *restrict s1, const void *restrict s2,
int c, size_t n);
DESCRIPTION
The memccpy () function shall copy bytes
from memory area s2 into s1, stopping
after the first occurrence of byte c (converted to an
unsigned
char) is copied, or after n bytes are copied,
whichever comes first. If copying takes place between objects that overlap,
the behavior is undefined.
RETURN VALUE
The memccpy () function shall return a
pointer to the byte after the copy of c in
s1, or a null pointer if c was not found
in the first n bytes of s2.
ERRORS
No errors are defined.
EXAMPLES
None.
APPLICATION USAGE
The memccpy () function does not check for
the overflow of the receiving memory area.
RATIONALE
None.
FUTURE DIRECTIONS
None.

The
restrict
keyword is added to the memccpy () prototype for
alignment with the ISO/IEC 9899:1999
