|
revoke(2) -- revoke file access
|
|
The revoke function invalidates all current open file descriptors in the system for the file named by path. Subsequent operations on any such descriptors fail, with the exceptions that a read() from a... |
|
rfork(2) -- control new processes
|
|
The fork functions (fork(2), vfork(2), and rfork()) create new processes. The new process (child process) is an exact copy of the calling process (parent process), except as outlined in the fork(2) ma... |
