dynamic_field_info, field_info - retrieve field characteristics
Синопсис (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, int *max);
Описание (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
option with field_opts_off.
Возвращаемое значение (Return value)

E_OK The routine succeeded.
E_SYSTEM_ERROR

Примечание (Note)
The header file <form.h> automatically includes the header file
<curses.h>.
Портативность (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.
