NAME

LIBRARY

     Curses Form Library (libform, -lform)

SYNOPSIS

     #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.

RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.  The functions that return an int will return one of the following
     error values:

     E_OK		The function was successful.

NAME

       form_field_validation, set_field_type, field_type, field_arg - forms field data type validation

SYNOPSIS

       cc [ flag... ] file... -lform  -lcurses	[ library... ]
       #include <form.h>

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

       FIELDTYPE *field_type(FIELD *field);

       char *field_arg(FIELD *field);

DESCRIPTION

       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.
