All of these host OS's (can) automatically mount the removable disk and access it without issues, and I'm looking for a way to detect that the host has ejected/unmounted the disk. The only way I...
Hello all, I am wondering how does stat command calculate the blocks of a file. I read the article, it says: The value st_blocks gives the size of the file in 512-byte blocks. (This may be smaller than st_size/512 e.g. when the file has holes.) The value st_blksize gives the "preferred" blocksize for efficient file system I/O. (Wri...
