Function Documentation

int rte_strsplit	(	char *	string,
		int	stringlen,
		char **	tokens,
		int	maxtokens,
		char	delim
	)

Takes string "string" parameter and splits it at character "delim" up to maxtokens-1 times - to give "maxtokens" resulting tokens. Like strtok or strsep functions, this modifies its input string, by replacing instances of "delim" with '\0'. All resultant tokens are returned in the "tokens" array which must have enough entries to hold "maxtokens".

Parameters

string	The input string to be split into tokens
stringlen	The max length of the input buffer
tokens	The array to hold the pointers to the tokens in the string
maxtokens	The number of elements in the tokens array. At most, maxtokens-1 splits of the string will be done.
delim	The character on which the split of the data will be done

Returns

The number of tokens in the tokens array.
