Hi all,

I have two routines, one saves a binary buffer, the other loads.

If I am in RHIDE, and run the program, I get a GPF if "length" is more than
49151.

If I am in DOS, and run the program, I get a GPF if "length" is more than
16383;

Here are the routines:

// begin //

void buffersave(char* filename, unsigned char* buffer, int length)
{
    int bc;
    FILE* fp = fopen(filename, "wb");

    for(bc=0;bc<length;bc++)
    {
        fputc(buffer[bc], fp);
    }

    fclose(fp);
}

void bufferload(char* filename, unsigned char* buffer, int length)
{
    int bc;
    FILE* fp = fopen(filename, "rb");

    for(bc=0;bc<length;bc++)
    {
        buffer[bc] = fgetc(fp);
    }

    fclose(fp);
}

// end //

I am running under Win98/DOS boxes.

I'm sure there is a simple solution. Any ideas?
