NAME
       form_field_buffer - field buffer control

SYNOPSIS
       #include <form.h>
       int set_field_buffer(FIELD *field, int buf, const char *value);
       char *field_buffer(const FIELD *field, int buffer);
       int set_field_status(FIELD *field, bool status);
       bool field_status(const FIELD *field);
       int set_max_field(FIELD *field, int max);

DESCRIPTION
       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  form_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.

RETURN VALUE
       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.

       tions of the entry points.

NOTES
       The  header  file  <form.h>  automatically  includes  the  header  file
       <curses.h>.

PORTABILITY
       These  routines emulate the System V forms library.  They were not sup‐
       ported on Version 7 or BSD versions.
