ncl_mpglty man page
MPGLTY — Retrieves the type of the line currently being drawn by MPLNDM.
CALL MPGLTY (ILTY)
void c_mpglty (int *ilty)
(an output variable of type INTEGER) is the type of the line: 1 => a line separating land from water, 2 => a line separating one "continent" from another (as, for example, Africa from Eurasia, North America from Central America, or Central America from South America), 3 => a line separating one country from another, 4 => a line separating one state from another, and 5 => a line separating one county from another. If the current line is used on more than one level (as, for example, a portion of the California coastline, which is used on all five levels), then the value of ILTY will be the smallest of the numerical values that apply.
The C-binding argument description is the same as the FORTRAN argument description.
MPGLTY may be called from within a line-processing routine whose name is used in a call to MPLNDM to retrieve, in ILTY, the type of the line being processed. This information may be used to determine how the line is to be drawn.
Use the ncargex command to see the following relevant example: mpex11.
To use MPGLTY or c_mpglty, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
