NAME

       mq_getsetattr - get/set message queue attributes

SYNOPSIS

       #include <sys/types.h>
       #include <mqueue.h>

       int mq_getsetattr(mqd_t mqdes, struct mq_attr *newattr,
                        struct mq_attr *oldattr);

       Note: There is no glibc wrapper for this system call; see NOTES.

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!)
