Interpretation Request #109
Topic: return type of mq_timedreceive() Relevant Sections: 220.127.116.11, Page 55, Line 72 of Draft 14 PASC
The return type of the new function mq_timedreceive() should be ssize_t, not int. This function was meant to be the functional equivalent of mq_receive() with the addition of a timeout capability. The ballot group failed to notice that the return type from the function was different from the original untimed function.
Change "int" in the synopsis line to "ssize_t".
The standards states that the return type for function mq_timedreceive() should be int, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor.
The return type is inconsistent with mq_receive().
Notes to Project Editor (not part of the interpretation)
