Creates a file with a unique name, in the current or specified
directory on the default or specified disk drive, and returns a
handle that can be used by the program for subsequent access to
the file. The name generated for the file is also returned in a
buffer specified by the program.

2) Files created with this function are not automatically deleted when the
caling program terminates.
3) The funciton fails if:
a) any element of the pathname does not exist.
b) The file is being created in the root directory and the root
directory is full.
4) If the program is running on a network, the file is created and opened
for read/write access in compatibility sharing mode.
5) See also Int\21f\3C and Int\21f\5B which provide additional
facilities for creating files.
