- v1.05 nmm 26-Jun-86 fn_exp - expand specification of list of file names
- returning in each successive call the next file name matching the input
- spec. The function expects that each in_spec passed
- to it will be processed to completion; in particular, up to and
- including the call following that in which the last matching name
- is returned, the function ignores the value of in_spec, and will
- only start processing a new spec with the following call.
- If an error occurs, on return out_spec contains the value
- of in_spec when the error occurred.
-
- With each successive file name returned in out_spec, the
- function's return value is one. When there are no more matching
- names the function returns zero. If on the first call no file
- matches in_spec, or there is any other error, -1 is returned.
