NAME

       mq_getattr - get status information and attributes associated with a message queue

SYNOPSIS

DESCRIPTION

       The  system  call  collects status information and attributes associated with the message queue specified by mqdes which is copied into the
       structure referenced by mqstat.

       Upon a successful return, the mq_msgsize and mq_maxmsg fields within the mq_attr structure contain the maximum size of a message  for  this
       queue  and the maximum number of messages that can be queued at any time. The mq_curmsgs field contains the number of messages currently on
       the queue. In addition, the mq_flags field contains the message queue blocking status associated with this mqdes.

       To use this function, link in the realtime library by specifying on the compiler or linker command line.
