Summary
The FILENAME_UNRESOLVE_ procedure accepts a file name as input, deletes left-
hand sections that match the default values, and returns a file name that is
semantically equivalent to the input file name.
Syntax for C Programmers
•
The character-string parameters longname and defaults are each followed by a
parameter
length that specifies the length in bytes of the character string. Where
the parameters are optional, the character-string parameter and the corresponding
length parameter must either both be supplied or both be absent.
