@ page 783 line 25660-25661 section mq_getattr() objection {jan-4191477}

Problem:

Defect code :  3. Clarification required

The errors section for mq_getattr() currently requires
that the function return -1 and set errno to EBADF if
mqdes is not a vaild message queue descriptor.
The message queue descriptor is of type mqd_t and the standard does
not specify this type defintion. An implementation could define
this type to be an interger type or a pointer type. If the latter
then any random pointer value could be passed as the message queue
descriptor to mq_getattr(). This could happen if a programming
error resulting in mq_getattr() being called without mq_open()
being called first. This error condition is akin to readdir() being
called without opendir() being called first. The standard does not
require that readdir() detect this condition, merely, that if
detected, -1 is returned and that errno be set to EBADF. The wording
for mq_getattr() should be changed to match readdir() because the
situations are analogous, see proposed solution.
