NAME    [Toc]    [Back]

       form_field_info - retrieve field characteristics

SYNOPSIS    [Toc]    [Back]

       #include <form.h>
       int field_info(const FIELD *field, int *rows, int *cols,
                     int *frow, int *fcol, int *nrow, int *nbuf);
       int dynamic_field_info(const FIELD *field, int *rows,  int
       *cols, *max);

DESCRIPTION    [Toc]    [Back]

       The  function  field_info  returns  the  sizes  and  other
       attributes passed in to the field at  its  creation  time.
       The  attributes are: height, width, row of upper-left corner,
 column of upper-left corner, number off-screen  rows,
       and number of working buffers.

       The function dynamic_field_info returns the actual size of
       the field, and its maximum possible size.   If  the  field
       has  no  size  limit,  the location addressed by the third
       argument will be set to 0.  (A field can be  made  dynamic
       by turning off the O_STATIC).

RETURN VALUE    [Toc]    [Back]

       These routines return one of the following:

       E_OK The routine succeeded.

       E_SYSTEM_ERROR    [Toc]    [Back]
            System error occurred (see errno).

       E_BAD_ARGUMENT    [Toc]    [Back]
            Routine  detected  an incorrect or out-of-range argument.

SEE ALSO    [Toc]    [Back]

       curses(3) and 3 pages whose names begin with  "form_"  for
       detailed descriptions of the entry points.

NOTES    [Toc]    [Back]

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

PORTABILITY    [Toc]    [Back]

       These routines emulate the System V forms  library.   They
       were not supported on Version 7 or BSD versions.

       A  null  (zero  pointer) is accepted for any of the return
       values, to ignore that  value.   Not  all  implementations
       allow this, e.g., Solaris 2.7 does not.
