pcntl_unshare

(PHP 7 >= 7.4.0, PHP 8)

pcntl_unshare — Dissociates parts of the process execution context

说明

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.

参数

flags

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

返回值

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