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 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.
These routines return one of the following:
The routine succeeded.
System error occurred (see errno).
Routine detected an incorrect or out-of-range argument.

descriptions of the entry points.
The header file <form.h> automatically includes the header file
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.
