pszName (PSZ) - input

An ASCIIZ string that contains the file name of the executable file for which the flags are to be returned.

If the string appears to be a fully qualified path (that is, it contains a " : " in the second position, or it contains a " \ ", or both), then the file is located in the indicated drive:directory. If neither of these is true, and this file name is not found in the current directory, each drive:directory specification in the path defined in the current program's environment is searched for this file. Note that any extension (.xxx) is acceptable for the executable file name. If no extension is specified, a default extension of ".exe" is used.
