Name

Type

Optional

Meaning

sPath

String

No

The directory path for the file name

sPrefix

String

No

The prefix string.
The function uses up to the first three characters of this string as the prefix of the file name.

uUnique

Number

Yes

An unsigned integer to be used in creating the temporary file name

If uUnique is zero, the function attempts to form a unique file name using the current system time. If the file already exists, the number is increased by one and the functions tests if this file already exists. This continues until a unique filename is found; the function creates a file by that name and closes it. Note that the function does not attempt to verify the uniqueness of the file name when uUnique is nonzero.
