- .SH NAME
- scan \- Parse string using sscanf-style conversions
- .SH SYNOPSIS
- \fBscan \fIstring format varName \fR?\fIvarName ...\fR?
- .BE

- .SH DESCRIPTION
- .PP
- This command parses fields from an input string in the same fashion
- as the C \fBsscanf\fR procedure and returns a count of the number
- of fields sucessfully parsed. \fIString\fR gives the input to
- be parsed and \fIformat\fR indicates how to parse it, using \fB%\fR
- fields as in \fBsscanf\fR. All of the \fBsscanf\fR options are valid;
- see the \fBsscanf\fR man page for details. Each \fIvarName\fR gives
- the name of a variable; when a field is scanned from \fIstring\fR,
- the result is converted back into a string and assigned to the
- corresponding \fIvarName\fR. The only unusual conversion is for
- \fB%c\fR. For \fB%c\fR conversions a single character value is
- converted to a decimal string, which is then assigned to the
- corresponding \fIvarName\fR;
- no field width may be specified for this conversion.
