#include <form.h> char * field_arg(FIELD *field); FIELDTYPE * field_type(FIELD *field); int set_field_type(FIELD *field, FIELDTYPE *type, ...); DESCRIPTION
The field_arg() function returns the field type arguments that are associated with the given field. The field_type() function returns the field type structure associated with the given field, this type can be set by calling the set_field_type() function which associates the given field type with the field, the third and subsequent parameters are field dependent arguments.

set_field_type() associates the specified field type with field. Certain field types take additional arguments. TYPE_ALNUM, for instance, requires one, the minimum width specification for the field. The other predefined field types are: TYPE_ALPHA, TYPE_ENUM, TYPE_INTEGER, TYPE_NUMERIC, and TYPE_REGEXP. field_type() returns a pointer to the field type of field. NULL is returned if no field type is assigned. field_arg() returns a pointer to the field arguments associated with the field type of field. NULL is returned if no field type is assigned. RETURN VALUES
field_type() and field_arg() return NULL on error. set_field_type() returns one of the following: E_OK The function returned successfully. E_SYSTEM_ERROR System error. ATTRIBUTES
