    SYNOPSIS

         #include <mqueue.h>
    
         int
         mq_getattr(mqd_t mqdes, struct mq_attr *mqstat);
    
    
    

    DESCRIPTION

         The mq_getattr() system call obtains status information and attributes of
         the message queue and the open message queue description associated with
         the message queue descriptor.
    
         The mqdes argument specifies a message queue descriptor.
    
         The results are returned in the mq_attr structure referenced by the
         mqstat argument.
    
         Upon return, the following members will have the values associated with
         the open message queue description as set when the message queue was
         opened and as modified by subsequent mq_setattr() calls: mq_flags.
    
         The following attributes of the message queue will be returned as set at
         message queue creation: mq_maxmsg, mq_msgsize.
    
         Upon return, the following members within the mq_attr structure refer-
         enced by the mqstat argument will be set to the current state of the mes-
         sage queue:
    
         mq_flags  The number of messages currently on the queue.
    
    
    

    RETURN VALUES

         Upon successful completion, the value 0 is returned; otherwise the
         value -1 is returned and the global variable errno is set to indicate the
         error.
