Splits a full path name into its components.
Defined in header <stdlib.h>

Remarks
_splitpatti takes a file's full path name (path) as a string in the form
X:\DIR\SUBDIR\NAME.EXT
and splits path into its four components. It then stores those components in the strings pointed to by drive, dir, name, and ext. (All five components must be passed, but any of them can be a null, which means the corre-sponding component will be parsed but not stored.)
| The maximum | sizes for these strings are given by the constants |
| _MAX_DRIVE, _MAX_DIR, _MAX_PATH, _MAX_FNAME, | and _MAX_EXT (defined |
in stdlib.h), and each size includes space for the null-terminator. These constants are defined in stdlib.h.
| Constant | Max | String |
| MAX PATH | (80) | path |
| MAX DRIVE | (3) | drive; includes colon (:) |
| _MAX_DIR | (66) | dir; includes leading and trailing backslashes (\) |
| MAX FNAME | (9) | name |
| _MAX_EXT | (5) | ext; includes leading dot (.) |
_splitpath assumes that there is enough space to store each non-null component.
When _splitpath splits path, it treats the punctuation as follows:
□ drive includes the colon (C:, A:, and so on). G dir includes the leading and trailing backslashes (\BC\include\, \ sourceX, and so on). D na7ne includes the file name. a ext includes the dot preceding the extension (.C, .EXE, and so on).
_makepath and _splitpath are invertible; if you split a given path with _splitpath, then merge the resultant components with _makepath, you end up with path.
Return value
None.
