.SH DESCRIPTION
.sp
.LP
\fBfield_info()\fR returns the size, position, and other named field
characteristics, as defined in the original call to \fBnew_field()\fR, to the
locations pointed to by the arguments \fIrows\fR, \fIcols\fR, \fIfrow\fR,
\fIfcol\fR, \fInrow\fR, and \fInbuf\fR.
.sp
.LP
\fBdynamic_field_info()\fR returns the actual size of the \fIfield\fR in the
pointer arguments \fIdrows\fR, \fIdcols\fR and returns the maximum growth
allowed for \fIfield\fR in \fImax\fR. If no maximum growth limit is specified
for \fIfield\fR, \fImax\fR will contain 0. A field can be made dynamic by
turning off the field option \fBO_STATIC\fR.
