<H2>DESCRIPTION</H2><PRE>
|
|
|
|
|
The function <STRONG>field_info</STRONG> 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 <STRONG>dynamic_field_info</STRONG> 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 <STRONG>O_STATIC</STRONG>).
