| pure logical function | is_absolute (filepath) |
| | Returns .true. if the path is absolute. On Unix a path is absolute when it starts with '/'. On Windows a path is absolute when it starts with a drive letter followed by ':\C:\', 'd:/temp').
|
| |
| pure logical function | is_rooted (filepath) |
| | Returns .true. if the path is rooted (starts with a separator) or is absolute. A rooted path begins with the platform separator ('\' on Windows, '/' elsewhere) even if it is not a full absolute path (e.g. '/temp' on Linux).
|

| pure character(:) function, allocatable | filename (filepath, keepext) |
| | Extracts the filename part of a path. By default the extension is stripped. If keepext=.true. the full filename including extension is returned.
|
| |
| pure character(:) function, allocatable | join_character_character (path1, path2) |
| | Joins two path components with the correct platform separator. Removes duplicate separators and trailing/leading whitespace.
|
| |
| pure character(:) function, allocatable | join_character_string (path1, path2) |
| | Joins character path with string path component. Removes duplicate separators and trailing/leading whitespace.
|
| |
| pure character(:) function, allocatable | join_string_character (path1, path2) |
| | Joins string path with character path component. Removes duplicate separators and trailing/leading whitespace.
|
| |
| pure character(:) function, allocatable | join_string_string (path1, path2) |
| | Joins two string path components. Removes duplicate separators and trailing/leading whitespace.
|
| |
| pure character(:) function, allocatable | dirpath (filepath) |
| | Returns the directory part of a path (everything before the last separator).
|
| |
| pure character(:) function, allocatable | dirname (filepath) |
| | Returns the base name (filename) part of a path.
|
| |
| pure subroutine | split_path (filepath, head, tail) |
| | Splits a path into head (directory) and tail (basename) components.
|
| |
| character(:) function, allocatable | cwd () |
