The function <STRONG>field_info</STRONG> returns the sizes and other
|
2015-12-06 09:07:45 +08:00
|
|
|
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,
|
1997-05-15 12:00:00 +08:00

|
and number of working buffers.

|
|
|
|
2002-10-13 11:35:53 +08:00

The function <STRONG>dynamic_field_info</STRONG> returns the actual size of
|
2015-12-06 09:07:45 +08:00
|
|
|
the field, and its maximum possible size. If the field
|
|
|
|
|
has no size limit, the location addressed by the third
|
2005-10-10 02:41:57 +08:00
|
|
|
argument will be set to 0. A field can be made dynamic by
|
|
|
|
|
turning off the <STRONG>O_STATIC</STRONG> option with <STRONG>field_opts_off</STRONG>.

These routines emulate the System V forms library. They

1997-05-15 12:00:00 +08:00

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
|
2000-07-09 10:46:08 +08:00
|
|

allow this, e.g., Solaris 2.7 does not.
