WAIT_OPTION Enumeration

Contains values that indicate the action a host should take if an operation requested by the common language runtime (CLR) blocks.

typedef enum {

    WAIT_NOTINDEADLOCK = 0x4,
} WAIT_OPTION;

Description

WAIT_ALERTABLE

Notifies the host that the task should be awakened if the CLR calls the IHostTask::Alert method.

WAIT_MSGPUMP

Notifies the host that it must pump messages on the current OS thread if the thread becomes blocked. The runtime specifies this value only on an STA thread.

WAIT_NOTINDEADLOCK

Notifies the host that the specified synchronization request cannot be broken by a host. That is, the host cannot return HOST_E_DEADLOCK.

The IHostTaskManager::Sleep and IHostTaskManager::SwitchToTask methods both take a parameter of this type.
