DESCRIPTION

Do not use this system call.

This is the low-level system call used to implement mq_getattr(3) and mq_setattr(3). For an explanation of how this system call operates, see the description of mq_setattr(3).

CONFORMING TO

This interface is nonstandard; avoid its use.

NOTES

Glibc does not provide a wrapper for this system call; call it using syscall(2). (Actually, never call it unless you are writing a C library!)
