Underspecified Aspects of Threads in C

To provide a standard method for using threads in C, a threads interface had been added to C11. It unifies various existing application programming interfaces (APIs) so that software developers could write portable multithreading code. C11 threads were deliberately defined with the least constraints such that they could be implemented as a standard veneer over native threads of a given platform. However, in some cases too much was left out of the specification. This document lists such cases and tracks the proposed solutions by the C standards committee
