In my system,i get SD card with two file system,one is FAT32 and another is QNX6.SD card is attach in file [/dev/hd1],
After executed [mount -e /dev/hd1], i got [ hd1t14] and [hd1t179] in path [dev].
 now i search in [dev] path to find some files that's name started with [hd1t],is there any better way to find it?
 I try send [DCMD_FSYS_MOUNTED_ON] use devctl function,but only can get [/dev/hd1] form [/dev/hd1t14].
