Summary:
In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version
7.0, the documentation for the functions tmpnam() 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 online help for C 6.0 and page 611 of the "Microsoft C for the
MS-DOS Operating System Run-Time Library Reference" for C 5.1 state
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(). These two defines are provided only for XENIX/UNIX
portability. The two functions tmpnam() and tempnam() do not make use
of these two defines.
