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

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

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

       IAIP        is an input expression of type INTEGER, specifying the area identifier of a  second  area  of
                   interest.

       None.

       MPIPAI - Given the area identifiers of two of the areas defined by whatever database was last read by the
       EZMAPB routines MPLNAM, MPLNDM, MPLNDR, and MPLNRI, this function has a non-zero value if and only if the
       first area is a part of the second.

       IPRT=MPIPAI(IAIN,IAIP)

       The  statement "IPRT=MPIPAI(IAIN,IAIP)" sets IPRT non-zero if and only if the area having area identifier
       IAIN is a part of the area having area identifier IAIP.  For example, if IMAD is the area  identifier  of
       the little island in Lake Superior called "Lake Madeline", ICUS is the area identifier of the area called
       'Conterminous  US',  and  IRUS is the area identifier of the area called 'Russia', then MPIPAI(IMAD,ICUS)
       has a non-zero value, but MPIPAI(IMAD,IRUS) does not.
