pREPC+ System Calls tmpnam
tmpnam Generates a temporary filename.

Description
Arguments
Return Value
Error Codes
The tmpnam() function generates a string that is intended to be used as a filename.
tmpname() generates up to 1000 unique names for each task. The pREPC+ library
does not maintain a list of tmpnames in use. After 1000 names have been
generated, the sequence starts over.
A file with a name generated by tmpnam() is not necessarily a temporary file. To be
treated as a temporary file, it must be created by tmpfile().
s Points to the string where tmpname() stores the filename.
When tmpname() is called, s should consist of the initial part of a
valid pathname. tmpname() adds a slash (/), followed by a T (or G if
the creating task is global). The T (or G) is followed by the lower 16bits
of the caller's task ID, which is followed by a decimal point and a
decimal number within the range 0 through 999.
For example, assume that s points to the string 0.0; the caller's tid is
00000002; and the caller has previously called tmpname() 12 times.
The generated name is 0.0/T0002.012.
This function returns a pointer to the generated name.
