It's not as long as I thought...so here it is. The bit about strcmp and
constants at the end is just how I wanted it for a particular program,
and can be excised.

/*
* Function to determine the type of file system on the drive specified

static enum FS_T fstype(PUCHAR path)
{ UCHAR fsqbuf[FSQBUFSIZE];
PUCHAR p;
ULONG fsqbuflen = FSQBUFSIZE;
UCHAR drv[3];
if(path[1] != ':') { /* No drive in path - use default */
curdrv(drv);
} else {
drv[0] = path[0];
drv[1] = path[1];
drv[2] = '\0';
}
if(DosQueryFSAttach(
drv,
0,
FSAIL_QUERYNAME,
(PFSQBUFFER2) fsqbuf,
&fsqbuflen) != 0)
return(FS_FAT);
/* Set 'p' to point to the file system name */
p = fsqbuf + sizeof(USHORT); /* Point past device type */
p += (USHORT) *p + 3*sizeof(USHORT) + 1;
/* Point past drive name and FS name */
/* and FSDA length */
if(strcmp(p, "CDFS") == 0) return(FS_CDFS);
if(strcmp(p, "CDWFS") == 0) return(FS_CDWFS);
if(strcmp(p, "HPFS") == 0) return(FS_HPFS);
if(strcmp(p, "NFS") == 0) return(FS_NFS);
return(FS_FAT);
}
