form_field_buffer: set_field_buffer, field_buffer, set_field_status, field_status, set_max_field -- set and get forms field attributes

Synopsis

cc [flag . . .] file -lform -locurses [library . . .]

#include <form.h>

int set_field_buffer(FIELD *field, int buf, char *value); char *field_buffer(FIELD *field, int buf); int set_field_status(FIELD *field, int status); int field_status(FIELD *field); int set_max_field(FIELD *field, int max);

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.

<Return> value

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 - The function returned successfully.
E_SYSTEM_ERROR - System error.
E_BAD_ARGUMENT - An argument is incorrect.

 E_OK             -   The function returned successfully.
 E_SYSTEM_ERROR   -   System error.
