<H2>DESCRIPTION</H2>
|
|
|
|
Do not use this system call.
|
|
<P>
|
|
|
|
This is the low-level system call used to implement
|
|
<B><A HREF="/cgi-bin/man/man2html?3+mq_getattr">mq_getattr</A></B>(3)
|
|
|
|
and
|
|
<B><A HREF="/cgi-bin/man/man2html?3+mq_setattr">mq_setattr</A></B>(3).
|
|
|
|
For an explanation of how this system call operates,
|
|
see the description of
|
|
<B><A HREF="/cgi-bin/man/man2html?3+mq_setattr">mq_setattr</A></B>(3).

<H2>NOTES</H2>
|
|
|
|
Glibc does not provide a wrapper for this system call; call it using
|
|
<B><A HREF="/cgi-bin/man/man2html?2+syscall">syscall</A></B>(2).
|
|
|
|
(Actually, never call it unless you are writing a C library!)
