mq_setattr(3c)

Standard C Library Functions                                    mq_setattr(3C)



NAME
       mq_setattr - set/get message queue attributes

SYNOPSIS
       #include <mqueue.h>

       int mq_setattr(mqd_t mqdes, const struct mq_attr *mqstat,
            struct mq_attr *omqstat);

DESCRIPTION
       The mq_setattr() function is used to set attributes associated with the
       open message queue description referenced by the message queue descrip‐
       tor specified by mqdes.


       The  message  queue  attributes  corresponding to the following members
       defined in the mq_attr structure are set to the specified  values  upon
       successful completion of mq_setattr():

       mq_flags    The value of this member is either 0 or O_NONBLOCK.



       The  values  of  mq_maxmsg,  mq_msgsize,  and mq_curmsgs are ignored by
       mq_setattr().


       If omqstat is non-NULL, mq_setattr() stores, in the location referenced
       by omqstat, the previous message queue attributes and the current queue
       status. These values are the same as would be returned  by  a  call  to
       mq_getattr() at that point.

RETURN VALUES
       Upon  successful  completion, mq_setattr() returns 0 and the attributes
       of the message queue will have been changed  as  specified.  Otherwise,
       the message queue attributes are unchanged, and the function returns −1
       and sets errno to indicate the error.

ERRORS
       The mq_setattr() function will fail if:

       EBADF     The mqdes argument is not a valid message queue descriptor.


       ENOSYS    The mq_setattr() function is not supported by the system.
