voidg2c_gbit_int(unsignedchar*in,int*iout,intiskip,intnbits)
       Extract arbitrary size values from a packed bit string, right justifying each value in the unpacked iout
       array. This is similar to gbit(), but with int types instead of g2int.

       Parametersin pointer to character array input.
           iout pointer that gets the unpacked array output.
           iskip initial number of bits to skip.
           nbits number of bits to take.

   intg2c_gbits_int(unsignedchar*in,int*iout,intiskip,intnbits,intnskip,intn)
       Extract arbitrary size values from a packed bit string, right justifying each value in the unpacked iout
       array. This is similar to gbits(), but with int types instead of g2int.

       Parametersin Pointer to character array input.
           iout Pointer that gets the unpacked array output.
           iskip Initial number of bits to skip.
           nbits Number of bits to take.
           nskip Additional number of bits to skip on each iteration.
           n Number of iterations.

       Returns

           • G2C_NOERROR No error.

           • G2C_ENOMEM Out of memory.
