pcntl_unshare - Dissociates parts of the process execution context

pcntl_unshare( int$flags ): bool

pcntl_unshare allows a process to disassociate parts of its execution context that are currently being shared with other processes. The main use of pcntl_unshare is to allow a process to control its shared execution context without creating a new process.



The flags parameter is a bitmask that specifies which parts of the execution context should be unshared. This parameter is specified by ORing together zero or more of the CLONE_* constants: CLONE_NEWNS CLONE_NEWIPC CLONE_NEWUTS CLONE_NEWNET CLONE_NEWPID CLONE_NEWUSER CLONE_NEWCGROUP

Return Values

Returns 0 on success, -1 otherwise. On failure it sets an error code, that can be retrieved with pcntl_get_last_error.
