NAME

       MPIOLA - Given the area identifier of one of the areas defined by whatever database was
       last read by one of the EZMAPB routines MPLNAM, MPLNDM, MPLNDR, and MPLNRI, this function
       returns the area identifier of the largest area, at a specified level, that contains it.

SYNOPSIS

       IOLA=MPIOLA(IAIN,ILVL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       int c_mpiola (int iaid, int ilvl)

DESCRIPTION

       IAIN        is an input expression of type INTEGER, specifying the area identifier of a
                   particular area of interest.

       ILVL        is an input expression of type INTEGER, specifying the level of the containing
                   area to be found.

C-BINDING DESCRIPTION

       The C-binding argument description is the same as the FORTRAN argument description.

USAGE

       The statement "IOLA=MPIOLA(IAIN,ILVL)" retrieves in IOLA the area identifier of the
       largest area, at level ILVL, that contains the area with area identifier IAIN.  For
       example, if IMAD is the area identifier of the little island in Lake Superior called "Lake
       Madeline", then MPIOLA(IMAD,3) is the area identifier of an area called "United States".

EXAMPLES

       Use the ncargex command to see the following relevant examples: mpex11, mpex12.

ACCESS

       To use MPIOLA or c_mpiola, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.
