.TH GETFIELDS 10.2
.SH NAME
getfields, tokenize \- break a string into fields
.SH SYNOPSIS
.ta \w'\fLchar* \fP'u
.B
int getfields(char *str, char **args, int maxargs, int multiflag,
.br
.B
char *delims)
.PP
.B
int tokenize(char *str, char **args, int maxargs)
.SH DESCRIPTION
.I Getfields
breaks the null-terminated
.SM UTF
string
.I str
into at most
.I maxargs
null-terminated fields and places pointers to the start of these fields in the array
.IR args .
Some of the bytes in
.I str
are overwritten.
If there are more than
.I maxargs
fields,
only the first
.I maxargs
fields will be set.
.I Delims
is a
.SM UTF
string defining a set of delimiters.
.PP
If
.I multiflag
is zero,
adjacent fields are separated by exactly one delimiter.
A string containing
.I n
delimiter characters
contains
.IR n +1
fields.
If the
.I multiflag
argument is not zero,
a field is a non-empty string of non-delimiters.
.PP
Getfields
return the number of tokens processed.
.PP
.I Tokenize
is the same as
.I getfields
with
.I multiflag
non-zero and
.I delims
\f5"\et\er\en "\fP,
except that fields may be quoted using single quotes, in the manner
of
the command interpreter.
