| .SH DESCRIPTION |
| These are building blocks for the form library, |
| defining fields that can be created using \fBset_fieldtype\fP(3X). |
| Each provides functions for field- and character-validation, |
| according to the given datatype. |
| .SS TYPE_ALNUM |
| This holds alphanumeric data. |
| .SS TYPE_ALPHA |
| This holds alphabetic data. |
| .SS TYPE_ENUM |
| This holds an enumerated type. |
| .SS TYPE_INTEGER |
| This holds a decimal integer. |
| .SS TYPE_IPV4 |
| This holds an IPv4 internet address, e.g., "127.0.0.1". |
| .SS TYPE_NUMERIC |
| This holds a decimal number, with optional sign and decimal point. |
| .SS TYPE_REGEXP |
| This holds a regular expression. |
| .SH PORTABILITY |
| The \fBTYPE_IPV4\fP variable is an extension not provided by older |
| implementations of the form library. |
| .SH SEE ALSO |
| \fBform\fR(3X). |
