tmpnam_r(3) Guardian Native C Library Calls Reference Manual
• Include the stdio.h file
To use the Standard POSIX Threads library, you must:
• Include the spthread.h file
• Link your application to the Standard POSIX Threads library:
/G/system/sysnn/zsptsrl (G-series)
or
/G/system/zdllnnn/zsptdll (H-series or J-series)
• Compile your application using the #define_SPT_MODEL_ macro or an equivalent
compiler command option.
For more detailed information about writing multi-threaded or 64- bit applications for the Open
System Services environment, see the Open System Services Programmer’s Guide.
RETURN VALUES
If the buf parameter is not a null pointer, it is assumed to be the address of an array of at least the
number of bytes specified by L_tmpnam. L_tmpnam is a constant defined in the stdio.h header
file. The tmpnam_r() function places its results into that array and returns the value of the buf
parameter.
If buf is a null pointer, the function returns NULL. This behavior differs from that of the
tmpnam( ) function.
RELATED INFORMATION
Functions: tmpnam(3), tmpnam_guardian(3), tmpnam_oss(3).
