◆ CreatePowrProfSemaphoreSecurity()

static BOOLEAN CreatePowrProfSemaphoreSecurity ( _Out_ PSECURITY_DESCRIPTOR PowrProfSd)
static

Creates a security descriptor for the power management registry semaphore.

Parameters
[out]PowrProfSdA pointer to an allocated security descriptor for the semaphore.
Returns
Returns TRUE if the function succeeds, otherwise FALSE is returned.
Remarks
Authenticated users are only given a subset of specific rights for the semaphore access, local system and admins have full power.
