Return Value

Parameters

path

Full path

drive

Optional drive letter, followed by a colon (:)

dir

Optional directory path, including trailing slash. Forward slashes ( / ), backslashes ( \ ), or both may be used.

fname

Base filename (no extension)

ext

Optional filename extension, including leading period (.)

Remarks

The _splitpath function breaks a path into its four components. _splitpath automatically handles multibyte-character string arguments as appropriate, recognizing multibyte-character sequences according to the multibyte code page currently in use. _wsplitpath is a wide-character version of _splitpath; the arguments to _wsplitpath are wide-character strings. These functions behave identically otherwise.

Generic-Text Routine Mappings

Each argument is stored in a buffer; the manifest constants _MAX_DRIVE, _MAX_DIR, _MAX_FNAME, and _MAX_EXT (defined in STDLIB.H) specify the maximum size necessary for each buffer. The other arguments point to buffers used to store the path elements. After a call to _splitpath is executed, these arguments contain empty strings for components not found in path. You can pass a NULL pointer to _splitpath for any component you don’t need.
