NAME

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

SYNOPSIS

#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.

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:
