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¶
