Purpose

Function to return temporary file name function

Description

The TMPNAM() function creates a temporary file and returns a character string containing the filename. By default, filenames returned by the TMPNAM() function have the extension ".tmp". The TMPNAM() function is particularly useful in multi-user applications where a unique temporary file can be created for each user process. The optional argument <expC1> specifies a directory where the temporary filename will created. The optional argument <expC2> specifies a file extension to use other than the default one of '.tmp'.

Note: if <expC1> is not specified and SET TMPNAMPATH is ON (default), the file will be created in the DB_TMPDIR directory and the filename returned will include the full path. If SET TMPNAMPATH is OFF, only the filename will be returned and the file will be created in the current directory. This behavior can also be achieved using the optional logical parameter <expL>. If <expL> is .F. (False), only the filename will be returned, if .T. (True), the full path will be returned.

Example

name = tmpnam( tmpdir(), ".txt")
report form Listing for event = "BALLET" to file &name
print &name
delete file &name
