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 form_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  deci-
       mal 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.
