retrieve field characteristics 

Curses Function

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 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).
