.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.

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
|
2005-10-10 02:41:57 +08:00
|
|
|
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.
