fp_get_files()

int fp_get_files	(	FilePicker *	filepicker,
		char *	path,
		int	get_dirs,
		int	get_files
	)

fp_get_files - fill file_names and dir_names with the results from readdir path

Parameters

*filepicker	- pointer to the struct holding the list pointers
*path	- the path to read from
get_dirs	- 0 = only read files 1 = refill the directory buffer as well
get_files	- 0 = only read directorys 1 = refill the file buffer as well

Returns

int - return the position of the given path in the directory list
