ISO C Threads (The GNU C Library)

### 36.1 ISO C Threads ¶

This section describes the GNU C Library ISO C threads implementation. To have a deeper understanding of this API, it is strongly recommended to read ISO/IEC 9899:2011, section 7.26, in which ISO C threads were originally specified.

All types and function prototypes are declared in the header file `threads.h`. When compiling for C, some functionality is also available in `stdlib.h`.

It is recommended that GNU systems use the functionality in `pthread.h` instead of `thread.h`, as they are more portable between C and C++.
