I presume you mean "tmpnam()" here.  No, it has not been deprecated -
not even in C23.  I could be wrong, but this sounds like one of MSVC's
arbitrary self-declared deprecations, using scare tactics to encourage
people to use MSVC's own functions rather than standard C functions,
thus locking you into their tools and platform.

You're right, tmpnam() is not deprecated either by ISO C or by POSIX.

But tmpfile() is likely to be better for most purposes.  It creates a
file and returns a FILE*.  tmpnam() returns a string pointer, and it's
possible that some other process could create a file with the same name
before the caller has a chance to create it.

(mkstemp() is more flexible, but is not defined by ISO C.)
