G_list_element()

void G_list_element	(	const char *	element,
		const char *	desc,
		const char *	mapset,
		int(*)(const char *, const char *, const char *)	lister
	)

General purpose list function.

Will list files from all mapsets in the mapset list for a specified database element.

Note: output is to stdout piped thru the more utility

lister (char *name char *mapset, char* buf)

Given file name, and mapset, lister() should copy a string into 'buf' when called with name == "", should set buf to general title for mapset list.

Parameters

element	database element (eg, "cell", "cellhd", etc.)
desc	description for element (if NULL, element is used)
mapset	mapset to be listed "" to list all mapsets in mapset search list "." will list current mapset
lister	if given will call this routine to get a list title. NULL if no titles desired.
