MQ_GETSETATTR(2) Linux Programmer's Manual MQ_GETSETATTR(2)

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!)
