pcntl_unshare
Description
The pcntl_unshare of PCNTL for PHP dissociates parts of the process execution context.
Syntax
pcntl_unshare(
int $flags
): boolParameters
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, and CLONE_NEWCGROUP.
Return
Returns 0 on success, -1 otherwise. On failure it sets an error code, that can be retrieved with pcntl_get_last_error().
