/**

Expand the wildcard by matching against the filesystem.
|
|
|
|
New strings are allocated using malloc and should be freed by the caller.
|
|
|
|
wildcard_expand works by dividing the wildcard into segments at
|
|
each directory boundary. Each segment is processed separatly. All
|
|
except the last segment are handled by matching the wildcard
|
|
segment against all subdirectories of matching directories, and
|
|
recursively calling wildcard_expand for matches. On the last
|
|
segment, matching is made to any file, and all matches are
|
|
inserted to the list.
|
|
|
|
If wildcard_expand encounters any errors (such as insufficient
|
|
priviliges) during matching, no error messages will be printed and
|
|
wildcard_expand will continue the matching process.
