The function set_field_buffer sets the numbered buffer of the given field to contain a given string. Buffer 0 is the displayed value of the field; other numbered buffers may be allocated by applications through the nbuf argument of (see field_new(3X)) but are not manipulated by the forms library. The function field_buffer returns the foreground attribute.
The function set_field_status sets the associated status flag of field; field_status gets the current value. The status flag is set to a nonzero value whenever the field changes.
The function set_max_field sets the maximum size for a dynamic field. An argument of 0 turns off any maximum size threshold for that field.
The field_buffer function returns NULL on error.
The field_status function returns TRUE or FALSE.
The remaining routines return one of the following:
|
E_OK |
The routine succeeded. |
E_SYSTEM_ERROR
System error occurred (see errno).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.

The header file <form.h> automatically includes the header file <curses.h>.
These routines emulate the System V forms library. They were not supported on Version 7 or BSD versions.
