NAME

       MPIOSA - 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 smallest area, at a specified level, that contains it.

SYNOPSIS

       IOSA=MPIOSA(IAIN,ILVL)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       int c_mpiosa (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 "IOSA=MPIOSA(IAIN,ILVL)" retrieves in IOSA the area identifier of that 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
       MPIOSA(IMAD,3) is the area identifier of the area called "Conterminous US".

EXAMPLES

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

ACCESS

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