form_field_info - retrieve field characteristics
#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);
The function field_info returns the sizes and other attri-
butes 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.
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 argument.
curses(3) and related pages whose names begin "form_" for
detailed descriptions of the entry points.
The header file <form.h> automatically includes the header
file <curses.h>.
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.
