set_field_buffer() sets buffer buf of field to value. Buffer 0 stores the displayed contents of the field. Buffers other than 0 are application specific and not used by the forms library routines. field_buffer() returns the value of field buffer buf.
Every field has an associated status flag that is set whenever the contents of field buffer 0 changes. set_field_status() sets the status flag of field to status. field_status() returns the status of field.
set_max_field() sets a maximum growth on a dynamic field, or if max=0 turns off any maximum growth.
field_buffer() returns NULL on error.
field_status() returns TRUE or FALSE.
set_field_buffer(), set_field_status(), and set_max_field() return one of the following:
E_OK Thefunction returned successfully.
E_SYSTEM_ERROR System error
E_BAD_ARGUMENT An argument is incorrect.
