SUMMARY
In Microsoft C, the documentation for the functions tmpnam(), tempnam() and _tempnam() states that under certain conditions they create a name that consists of the path prefix defined by the P_tmpdir entry in STDIO.H. This is ambiguous. A better way of stating this is that they create a name that consists of a path prefix to the root of the current drive; this is also what P_tmpdir is defined as. However, P_tmpdir is defined as the root directory on the default drive, which is where the created name would reside. However, any modification of P_tmpdir in STDIO.H does not change the filename that is created.
The documentation states that changing the definition of P_tmpdir or L_tmpnam does not change the operation of tmpnam(). Nor does it change the operation of tempnam() or _tempnam(). These two defines are provided only for XENIX/UNIX portability. The three functions tmpnam(), tempnam() and _tempnam() do not make use of these two defines.
