DESCRIPTION
The C run-time library supports two variants of the tmpnam( ) function: tmpnam_oss( ) and
tmpnam_guardian( ). The variants support the unique file naming conventions and structures of
the OSS and Guardian file systems, respectively.
The header file maps calls to tmpnam( ) to the variant that matches the target compilation
environment. The target environment is set with the systype pragma.
Explicit calls to the tmpnam_oss( ) and tmpnam_guardian( ) variants in source code are only
made when the behavior of one environment is desired from the other environment.
For a description of the tmpnam( ) OSS function and the tmpnam_oss( ) function, refer to the
tmpnam_oss(3) reference page. For a description of the tmpnam( ) Guardian function and the
tmpnam_guardian( ) function, refer to the tmpnam_guardian(3) reference page.
