form_field_info - retrieve field characteristics
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 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).
These routines return one of the following:
E_OK The routine succeeded.
System error occurred (see errno).

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.
