Return values If the system call succeeds the return value is 0. If the system call fails the return value is one of the following errno values:
`-EACCES` | `Write access to the directory containing pathname was not allowed, or one of the directories in the path prefix of pathname did not allow search permission.`
`-EBUSY` | `Pathname is currently used as a mount point or is the root directory of the calling process.`
`-EFAULT` | `ebx outside your accessible address space.`
`-EINVAL` | `Pathname has . as last component.`
`-ELOOP` | `Too many symbolic links were encountered in resolving pathname.`
`-ENAMETOOLONG` | `Pathname was too long.`
`-ENOENT` | `A directory component in pathname does not exist or is a dangling symbolic link.`
`-ENOMEM` | `Insufficient kernel memory was available.`
`-ENOTDIR` | `Pathname, or a component used as a directory in pathname, is not, in fact, a directory.`
`-ENOTEMPTY` | `Pathname contains entries other than . and .. ; or, pathname has .. as its final component.`
`-EPERM` | `The directory containing pathname has the sticky bit (S_ISVTX) set and the process's effective user ID is neither the user ID of the file to be deleted nor that of the directory containing it, and the process is not privileged (does not have the CAP_FOWNER capability). -or- The filesystem containing pathname does not support the removal of directories.`
`-EROFS` | `Pathname refers to a file on a read-only filesystem.`
