.SH NAME
-\fBform_field_info\fR - retrieve field characteristics
+\fBform_field_info\fR \- retrieve field characteristics
.SH SYNOPSIS
\fB#include <form.h>\fR
.br
int field_info(const FIELD *field, int *rows, int *cols,
int *frow, int *fcol, int *nrow, int *nbuf);

.SH DESCRIPTION
The function \fBfield_info\fR 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.
-
+.PP
The function \fBdynamic_field_info\fR 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 \fBO_STATIC\fR).
+addressed by the third argument will be set to 0.
+A field can be made dynamic
+by turning off the \fBO_STATIC\fR option with \fBfield_opts_off\fR.
.SH RETURN VALUE
These routines return one of the following:
.TP 5
-\fBE_OK\fR
+.B E_OK
The routine succeeded.
.TP 5
-\fBE_SYSTEM_ERROR\fR
+.B E_SYSTEM_ERROR
System error occurred (see \fBerrno\fR).
.TP 5
-\fBE_BAD_ARGUMENT\fR
+.B E_BAD_ARGUMENT
Routine detected an incorrect or out-of-range argument.

+\fBcurses\fR(3X) and related pages whose names begin "form_" for detailed
descriptions of the entry points.
.SH NOTES
The header file \fB<form.h>\fR automatically includes the header file
.SH PORTABILITY
These routines emulate the System V forms library. They were not supported on
Version 7 or BSD versions.
+.PP
+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.
