DESCRIPTION

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.
