form_field_info(3X) Library calls form_field_info(3X)
dynamic_field_info, 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 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:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno(3)).
E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.
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.
