CreatePowrProfSemaphoreSecurity()

static BOOLEAN CreatePowrProfSemaphoreSecurity ( _Out_ PSECURITY_DESCRIPTOR *  PowrProfSd )

static

Creates a security descriptor for the power management registry semaphore.

Parameters

[out]

PowrProfSd

A 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.
