Actually you are. That function, _dpmi_go32_and_so_on_and_so_on is already
defined. The proper use of it in 30 seconds or less would be:

#include <stdio.h>
#include <dpmi.h>

int main()
{
    long int bytes;
    float answer;

    // get free memory in bytes
    bytes = _go32_dpmi_remaining_physical_memory();

    // calculate to decimal point megabyte
    answer = (float) bytes / (1024.0 * 1024.0);

    printf("%f megabytes of ram free\n", answer);
    return 0;
}

Don't define that function yourself, it's taken care of in the libraries.
