Drivers Scced

  

In this paper, we explore drivers, objectives, success factors, and implications of digital transformation. This investigation is conducted through a systematic literature review that focuses on.

Many kernel-mode standard driver routines and driver support routines use the NTSTATUS type for return values. Additionally, drivers provide an NTSTATUS-typed value in an IRP's IO_STATUS_BLOCK structure when completing IRPs. The NTSTATUS type is defined in Ntdef.h, and system-supplied status codes are defined in Ntstatus.h. (Vendors can also define private status codes, although they rarely need to. For more information, see Defining New NTSTATUS Values.)

NTSTATUS values are divided into four types: success values, informational values, warnings, and error values.

Numerous values are assigned to each type. A common mistake, when testing for a successful return from a routine, is to compare the routine's return value with STATUS_SUCCESS. This comparison checks for only one of several success values.

When testing a return value, you should use one of the following system-supplied macros (defined in Ntdef.h):

NT_SUCCESS(Status)
Evaluates to TRUE if the return value specified by Status is a success type (0 − 0x3FFFFFFF) or an informational type (0x40000000 − 0x7FFFFFFF).

NT_INFORMATION(Status)
Evaluates to TRUE if the return value specified by Status is an informational type (0x40000000 − 0x7FFFFFFF).

NT_WARNING(Status)
Evaluates to TRUE if the return value specified by Status is a warning type (0x80000000 − 0xBFFFFFFF).

NT_ERROR(Status)
Evaluates to TRUE if the return value specified by Status is an error type (0xC0000000 - 0xFFFFFFFF).

For example, suppose a driver calls IoRegisterDeviceInterface to register a device interface. If the driver checks the return value using the NT_SUCCESS macro, the macro will evaluate to TRUE if the routine returns STATUS_SUCCESS, which indicates no errors, or if it returns the informational status STATUS_OBJECT_NAME_EXISTS, which indicates that the device interface is already registered.

As another example, suppose a driver calls ZwEnumerateKey to enumerate the subkeys of a specified registry key. If the NT_SUCCESS macro evaluates to FALSE, it might be because the routine returned STATUS_INVALID_PARAMETER, which is an error code, or because the routine returned STATUS_NO_MORE_ENTRIES, which is a warning code.

As a final example, suppose a driver sends an IRP that causes a lower-level driver to read information from a device. If the requesting driver specifies a buffer that is too small to receive any information, the lower-level driver might respond by returning STATUS_BUFFER_TOO_SMALL, which is an error code. If the first driver specifies a buffer that can receive some, but not all, of the requested information, the lower-level driver might respond by supplying as much data as possible and then returning STATUS_BUFFER_OVERFLOW, which is a warning code. Note that if the first driver tests the status value using NT_SUCCESS or NT_ERROR incorrectly, it might inadvertently drop some of the information received.

The massive success of “Driver’s License” – a song by hitherto little-known eighteen year old singer-songwriter Olivia Rodrigo – was no accident, and offers signs of hope to songwriters everywhere.

Teenage star Olivia Rodrigo’s song “Driver’s License” is the biggest hit in the world right now, and its success points to a bright future for songwriters everywhere.

It seems like the news is happening too fast for anyone to follow in January 2021. Between the Capitol riots, vaccine distribution, and the presidential inauguration, life is moving fast. Nobody can blame you if music hasn’t been the first thing on your mind, but you really shouldn’t go much longer without experiencing Olivia Rodrigo’s new single, “Driver’s License.” Check it out:

“Driver’s License” is the biggest song in the world right now, and it is breaking new records with each passing day. The song recently set a single-day consumption record on Spotify with more than 17-million streams. It’s the most played track in dozens of countries, and its video has earned over 50-million views in less than two weeks. All this, for a singer-songwriter under the age of eighteen who until recently was relatively unknown to most of the world.

The success of “Driver’s License” is no fluke, but it results from several important factors coming together at the perfect moment in time. Rodrigo is a Gen Z star leading a Disney+ series with strong ties to social media, for starters. Her private life is well known to her young audience, and their belief in the starlet made the song a hit on TikTok as soon as its release. There is also a pop music drought resulting from the ongoing Pandemic, and that has left a wide-open field for new voices to gain attention.

But that’s not all. The forward momentum made possible by the factors above could only lift “Driver’s License” to the insane heights it is currently reaching if the song was good (and it is). The track taps into universal feelings of confusion, vulnerability, and heartache, anchored by a story revolving around a pivotal moment in human development that everyone recognizes. It’s a testament to the power of storytelling, and it defies the years of criticism pop music has received for being viewed as shallow or meaningless. “Driver’s License” has meaning, and it is resonating with listeners in a big way.
