.SH 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.
.SH SYNOPSIS
IOLA=MPIOLA(IAIN,ILVL)
.SH C-BINDING SYNOPSIS
#include <ncarg/ncargC.h>
.sp
int c_mpiola (int iaid, int ilvl)
.SH DESCRIPTION 
.IP IAIN 12
is an input expression of type INTEGER, specifying the area identifier of a
particular area of interest.
.IP ILVL 12
is an input expression of type INTEGER, specifying the level of the containing
area to be found.
.SH C-BINDING DESCRIPTION
The C-binding argument description is the same as the FORTRAN 
argument description.
.SH 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".
.SH EXAMPLES
Use the ncargex command to see the following relevant examples: mpex11, mpex12.
.SH ACCESS
To use MPIOLA or c_mpiola, load the NCAR Graphics libraries ncarg, ncarg_gks,
and ncarg_c, preferably in that order.
