/** Return the name of the file system component indicated by path

* @param path A file path
|
|
* @returns The name of the directory or file that the path points to, or the
|
|
* empty string if there's an error
|
|
*
|
|
* The exact behavior of this function is platform dependent, because paths are.
|
|
* However, whatever the platform, it should return the name of the file or
|
|
* directory pathed. Ex., on POSIX platforms it should return "readme.txt" for
|
|
* "/home/user/documents/readme.txt"; similarly it should return "readme.txt"
|
|
* for "C:\Windows\readme.txt" on Windows platforms.
|
|
*
|
|
* This function does not access the file system. It merely parses the string.
|
|
* In particular, it does not check if the path is valid and/or accessible. It
|
|
* also does not check that the component before "." or ".." is, in fact, a
|
|
* directory.
|
|
*
|
|
* If the last component cannot be determined for whatever reason, the string is
|
|
* considered malformed and the empty string is returned.
|
|
*
|
|
* @note Although the empty string is considered a malformed path, "." (and
|
|
* anything equivalent) will return ".".
