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,
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 NUL bytes.
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 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). Any such quotes remain in the resulting args. See quote(2) for related quote–handling software.
Tokenize is similar to gettokens with delims set to "\t\r\n ", except
that quotes are interpreted but do not appear in the resulting
args. |
