NAME

	getfields, gettokens, tokenize – break a string into fields

SYNOPSIS

	#include <u.h> #include <libc.h> int    getfields(char *str, char **args, int maxargs, int multiflag, char *delims) int    gettokens(char *str, char **args, int maxargs, char *delims) int    tokenize(char *str, char **args, int maxargs)

DESCRIPTION

Getfields places into the array args pointers to the first maxargs fields of the null terminated UTF string str. Delimiters between these fields are set to null. Fields are substrings of str whose definition depends on the value of multiflag. If multiflag is zero, adjacent fields are separated by exactly one delimiter. For example getfields("#alice#bob##charles###", arg, 3, 0, "#"); yields three substrings: null-string , alice, and bob##charles###. If the multiflag argument is not zero, a field is a non-empty string of non-delimiters. For example getfields("#alice#bob##charles###", arg, 3, 1, "#"); yields the three substrings: alice, bob, and charles###. Getfields returns the number of fields pointed to. Gettokens is the same as getfields with multiflag non-zero, except that fields may be quoted using single quotes, in the manner of rc(1). See quote(3) for related quote-handling software. Tokenize is gettokens with delims set to "\t\r\n ".
