int set_field_type(FIELD *field, FIELDTYPE *type...);

FIELDTYPE *field_type(FIELD *field);

char *field_arg(FIELD *field);

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.

field_type() and field_arg() return NULL on error.

set_field_type() returns one of the following:

E_OK

E_SYSTEM_ERROR
