.TH GETWORD 3 "March 5, 1985" "UNIX|STAT 5.0" "UNIX Programmer's Manual"
.SH NAME
getword \- get a word from a file pointer
.SH SYNOPSIS
.nf
char *
getword (string, ioptr);
char	*string;
FILE	*ioptr;
.fi
.SH DESCRIPTION
.PP
.I getword
is a faster substitute for using scanf(3) for reading strings.
It reads whitespace separated strings so that the following
cases are equivalent.
.nf
	getword (string, ioptr);
	fscanf (ioptr, "%s", string);
.fi
.SH DIAGNOSTICS
.I getword
returns NULL when no new string is obtained.
Otherwise it returns a pointer to the END of the returned string.
This can be used to obtain the length of the string
or to process the string from the end.
.SH EXAMPLE
.nf
	char	*string, *eptr;
	int 	len;
	if (eptr = getword (string, stdin))
		{
		len = eptr - string;
		...
.fi
