I am porting a DOS program to NY and trying to read the CDROM with the ANIS C functions open() read() lseek()...

Here is what I am trying to do.

/********************** siocons test ************/
#include <libps.h>
#include <sys/file.h>

main()
{

     int fd,ret;
    char f[] = "cdrom:\\DATA\\SOUND\\SAMPLE1.SEQ;1";
    char text[1000];

printf("trying to open %s\n",f);

     fd = open(f,O_RDONLY); // | O_NOWAIT | O_NBLOCK | O_NOBUF);     //   just incase

     if(fd > 0)
          printf("open worked fd = %d\n",fd);
     else
     {
          printf("open failed fd = %d\n",fd);
          return;
     }

printf("trying to read %s\n fd = %d\n",f,fd);

ret = read(fd,&text,999);

printf("ret = %d\n",ret);

text[999] = 0;

printf("File <%s> CONTAINS \n<%s>\n",f,text);

close(fd);
}

This compiles but hangs when it hits

fd = open(f,O_RDONLY); // | O_NOWAIT | O_NBLOCK | O_NOBUF); // just incase

When this is ran using

char f[] = "\\DATA\\SOUND\\SAMPLE1.SEQ;1"; // (no device - cdrom: )

it says that - \DATA\SOUND\SAMPLE1.SEQ;1 is not a device then

it displays all devices available eg bu: ,tty:, cdrom:
and exits.

What is the correct device name for the cdrom eg
cdrom??:

I really don't want to use the CdlFILE functions !
BTW how do you convert CdlLOC type to a int to create a seek fuction?

What did I miss?

Lots of thanks in advance!
