## NAME

           form_field_info - retrieve field characteristics

## SYNOPSIS

           #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

           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 cor-
           ner, 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

           These 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 argu-
                ment.

## SEE ALSO

           curses(3x) and 3x pages  whose  names  begin  "form_"  for
           detailed descriptions 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 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.
