Sun Studio 12: C User's Guide


Set this environment variable to TRUE to print warning messages from OpenMP and other parallelization runtime-systems.


If you registered a function by using sunw_mp_register_warn() to handle warning messages, then SUNW_MP_WARN prints no warning messages, even if you set it to TRUE. If you did not register a function and set SUNW_MP_WARN to TRUE, SUNW_MP_WARN prints the warning messages to stderr. If you do not register a function and you do not set SUNW_MP_WARN, no warning messages are issued. For more information on sunw_mp_register_warn() see 3.2.1 Handling OpenMP Runtime Warnings.
