NAME

TYPE_ALNUM, TYPE_ALPHA, TYPE_ENUM, TYPE_INTEGER, TYPE_IPV4, TYPE_NUMERIC, TYPE_REGEXP - form system global variables

SYNOPSIS

#include <form.h> FIELDTYPE * TYPE_ALNUM; FIELDTYPE * TYPE_ALPHA; FIELDTYPE * TYPE_ENUM; FIELDTYPE * TYPE_INTEGER; FIELDTYPE * TYPE_IPV4; FIELDTYPE * TYPE_NUMERIC; FIELDTYPE * TYPE_REGEXP;

DESCRIPTION

These are building blocks for the form library, defining fields that can be created using set_fieldtype(3X). Each provides functions for field- and character-validation, according to the given datatype. TYPE_ALNUM This holds alphanumeric data. TYPE_ALPHA This holds alphabetic data. TYPE_ENUM This holds an enumerated type. TYPE_INTEGER This holds a decimal integer. TYPE_IPV4 This holds an IPv4 internet address, e.g., "127.0.0.1". TYPE_NUMERIC This holds a decimal number, with optional sign and decimal point. TYPE_REGEXP This holds a regular expression.

PORTABILITY

The TYPE_IPV4 variable is an extension not provided by older implementations of the form library.
