The Claim_Critical_Section service increments the claim count by the specified value. It has the same effect as calling the Begin_Critical_Section service repeatedly.
Claims
Specifies the number of times to claim the critical section. Zero is a valid number, but is ignored.
Flags
Specifies actions to take when interrupts occur while the virtual machine is blocked waiting for the critical section. This parameter can be a combination of the following values:
| Value | Meaning |
| Block_Enable_Ints | Service interrupts in the virtual machine even if the virtual machine does not currently have interrupts enabled. This forces interrupts to be enabled. This value is only relevant if either Block_Svc_Ints or Block_Svc_If_Ints_Locked is set. |
| Block_Svc_If_Ints_Locked | Service interrupts in the virtual machine even if the virtual machine is blocked, and the VMStat_V86IntsLocked flag is set. |
| Block_Svc_Ints | Service interrupts in the virtual machine even if the virtual machine is blocked. |
The Block_Poll value is reserved and must not be used with this service.
This service has no return value.
Flags
Adjust_Exec_Priority, Begin_Critical_Section, End_Critical_Section
