threaded

Option Type Default Value #pragma options C C++
-qoption See Below - x x

Syntax

    -qthreaded | -qnothreaded

Purpose
Indicates to the compiler that the program will run in a multi-threaded environment. Always use this option when compiling or linking multi-threaded applications. This option ensures that all optimizations are thread-safe.

Notes
This option applies to both compile and linkage editor operations.

To maintain thread safety, a file compiled with the -qthreaded option, whether explicitly by option selection or implicitly by choice of _r compiler invocation mode, must also be linked with the -qthreaded option.

This option does not make code thread-safe, but it will ensure that code already thread-safe will remain so after compile and linking.

Default
The default is -qthreaded when compiling with _r invocation modes, and -qnothreaded when compiling with other invocation modes.
