Regular expression data. Requires a regular expres-
sion <STRONG>(char</STRONG> <STRONG>*)</STRONG> third argument; the data is valid if
the regular expression matches it. Regular expres-
- sions are in the format of <STRONG><A HREF="regcomp.3x.html">regcomp(3x)</A></STRONG> and
- <STRONG><A HREF="regexec.3x.html">regexec(3x)</A></STRONG>. Please notice that the regular expres-
- sion must match the whole field. If you have for
- example an eight character wide field, a regular
- expression "^[0-9]*$" always means that you have to
- fill all eight positions with digits. If you want to
- allow fewer digits, you may use for example "^[0-9]*
- *$" which is good for trailing spaces (up to an empty
- field), or "^ *[0-9]* *$" which is good for leading
- and trailing spaces around the digits.
