.SH NAME
CPLBDR - 
Draws labels (an informational label, high and
low labels, and line labels).
.SH SYNOPSIS
CALL CPLBDR (ZDAT, RWRK, IWRK)
.SH C-BINDING SYNOPSIS
#include <ncarg/ncargC.h>
.sp
void c_cplbdr (float *zdat, float *rwrk, int *iwrk)
.SH DESCRIPTION 
All three arguments are arrays used in the last call to 
CPRECT, CPSPS1, or CPSPS2, the contents of which must not 
have been changed since that call.
.IP ZDAT 12
(REAL array, dimensioned as specified in the last call 
to CPRECT, CPSPS1, or CPSPS2, input) is the data array.
.IP RWRK 12
(REAL array, dimensioned as specified in the last call 
to CPRECT, CPSPS1, or CPSPS2, input/output) is the real 
workspace array.
.IP IWRK 12
(INTEGER array, dimensioned as specified in the last 
call to CPRECT, CPSPS1, or CPSPS2, input/output) is the 
integer workspace array.
.SH C-BINDING DESCRIPTION
The C-binding argument descriptions are the same as the FORTRAN 
argument descriptions.
.SH USAGE
CPLBDR may be called at any time after the initialization 
call to CPRECT, CPSPS1, or CPSPS2. If, during the last 
call to CPRECT, CPSPS1, or CPSPS2, the data being 
contoured were found to be essentially constant, then the 
constant-field label is drawn. Otherwise, the 
information label, the high and low labels, and/or the 
contour line labels are drawn, as follows:
.IP \(bu
The information label is drawn only if the 
parameter 'ILT', which specifies the text of that label, is
not blank.
.IP \(bu
High labels are drawn only if the parameter 'HIT',
which specifies the text of those labels, is not blank.
.IP \(bu
Low labels are drawn only if the parameter 'LOT',
which specifies the text of those labels, is not blank.
.IP \(bu
Contour line labels are drawn only if the parameter 'LLP',
which specifies how those labels are to be
positioned, has an absolute value of 2 or 3, and if, for 
some I between 1 and 'NCL' inclusive, the Ith element of
the parameter array 'CLU' has a value implying that
contour lines at the contour level specified by the Ith 
element of 'CLV' are to be labeled.

and ncarg_c, preferably in that order.
