/***********************************************************************
* DIR_SearchAlternatePath
*
* Searches for a specified file in the search path.
*
* PARAMS
* dll_path [I] Path to search
* name [I] Filename to search for.
* ext [I] File extension to append to file name. The first
* character must be a period. This parameter is
* specified only if the filename given does not
* contain an extension.
* buflen [I] size of buffer, in characters
* buffer [O] buffer for found filename
* lastpart [O] address of pointer to last used character in
* buffer (the final '\') (May be NULL)
*
* RETURNS
* Success: length of string copied into buffer, not including
* terminating null character. If the filename found is
* longer than the length of the buffer, the length of the
* filename is returned.
* Failure: Zero
*
* NOTES
* If the file is not found, calls SetLastError(ERROR_FILE_NOT_FOUND)
