.SH DESCRIPTION
|
||
|
.LP
|
||
|
The \fImemccpy\fP() function shall copy bytes from memory area \fIs2\fP
|
||
|
into \fIs1\fP, stopping after the first occurrence of
|
||
|
byte \fIc\fP (converted to an \fBunsigned char\fP) is copied, or after
|
||
|
\fIn\fP bytes are copied, whichever comes first. If
|
||
|
copying takes place between objects that overlap, the behavior is
|
||
|
undefined.
|
||
|
.SH RETURN VALUE
|
||
|
.LP
|
||
|
The \fImemccpy\fP() function shall return a pointer to the byte after
|
||
|
the copy of \fIc\fP in \fIs1\fP, or a null pointer if
|
||
|
\fIc\fP was not found in the first \fIn\fP bytes of \fIs2\fP.
|
||
|
.SH ERRORS
|
||
|
.LP
|
||
|
No errors are defined.

|
||
|
None.
|
||
|
.SH APPLICATION USAGE
|
||
|
.LP
|
||
|
The \fImemccpy\fP() function does not check for the overflow of the
|
||
|
receiving memory area.
|
||
|
.SH RATIONALE
