Function Documentation

dict_scan()

int dict_scan	(	Dict	dict,
		char *	str,
		int *	before,
		int *	after,
		void *	client,
		int(*)(char *name, const char *info, int pos, void *client)	f
	)

dictionary scan

Parameters

dict	dictionary handle
str	start pint term (string-z)
before	number of terms to be visited preceding str
after	number of terms to be visited following str
client	client data pointer to be passed to match function f
f	function be called for each matching term

Return values

0	Successful
-1	error

If the callback function f returns 0 the scan operation visits all terms in range (before to after); if the function returns non-zero the scan operation is cancelled.
