Function Names
resolve path name, resolve directory name, resolve file nameDescription
This function resolves specified directory path and file names (containing wildcard symbols in various directory and/or file names) to existing path and file names where
1. The full path name will be checked.
- For resolve file name, the last name must be a file name.
- For resolve file name, the last name must be a directory name.
- For resolve path name, the last name may either be a file or directory name.
2. If path contains wildcard symbols (Attention: '*' and '?' only), then the matching name will be identified.
If 2 or more matches are found, then an exception will be asserted because the path is ambiguous.
3. If the path begins with a lone tilde symbol ('~/...', '~\...'), then the tilde will be replaced by the user home directory.
4. Wildcards along the full directory path are allowed, e.g. "C:\Prgram Files\*\*\Lib\Support Library*". B4P will search through the different
subdirectories accordingly.
Note:In interactive mode, B4P will automatically capture all 'cd' / 'chdir' / changing drive commands and take care of changing the
directores in the B4P process, too. Reason: Operating System commands executed happen in child processes and changing direcctories have no effect on their parent processes.
