This allows 68*0Sstevel@tonic-gate * non-standard names to be converted (.i.e., block device "/dev/joe" can 69*0Sstevel@tonic-gate * be converted to raw device "/dev/fred", via this mechanism). 70*0Sstevel@tonic-gate * 71*0Sstevel@tonic-gate * Last standard names are converted. Standard names are those 72*0Sstevel@tonic-gate * with a '/dsk/' for block or '/rdsk/' for raw sub-directory components 73*0Sstevel@tonic-gate * in the device name. Or, the filename component has an 'r' for raw or 74*0Sstevel@tonic-gate * no 'r' for block (e.g., rsd0a <=> sd0a). 75*0Sstevel@tonic-gate * 76*0Sstevel@tonic-gate * Caveat: 77*0Sstevel@tonic-gate * It is assumed that the block and raw devices have the 78*0Sstevel@tonic-gate * same device number, and this is used to verify the conversion 79*0Sstevel@tonic-gate * happened corretly. If this happens not to be true, due to mapping 80*0Sstevel@tonic-gate * of minor numbers or sometheing, then entries can be put in the 81*0Sstevel@tonic-gate * the '/etc/vfstab' file to over-ride this checking. 82*0Sstevel@tonic-gate * 83*0Sstevel@tonic-gate * 84*0Sstevel@tonic-gate * Return Values: 85*0Sstevel@tonic-gate * raw/block device name - (depending on which routine is used) 86*0Sstevel@tonic-gate * null string - When the conversion failed 87*0Sstevel@tonic-gate * null pointer - malloc problems 88*0Sstevel@tonic-gate * 89*0Sstevel@tonic-gate * It is up to the user of these routines to free the memory, of 90*0Sstevel@tonic-gate * the device name or null string returned by these library routines, 91*0Sstevel@tonic-gate * when appropriate by the application. 92*0Sstevel@tonic-gate */ 93*0Sstevel@tonic-gate #define GET_BLK 0 94*0Sstevel@tonic-gate #define GET_RAW 1 95*0Sstevel@tonic-gate 96*0Sstevel@tonic-gate static int test_if_blk(char *, dev_t);
