Detailed Description

Implements the miscellaneous functions defined in misc.h.

Function Documentation

HRESULT CheckCOMInitialization ( )

Simple check to see whether COM has been initialised for the current thread

std::wstring GetCurrentDateTime ( )

Returns the current date and time in the C locale

Calls time to get current UTC time, localtime to convert that, and then the wide strftime using the classic C locale to get the date/time string

DWORD GetCurrentTimerResolution ( )

Returns the current resolution of the system timer

The function queries the value set by timeBeginPeriod, in essence it is timeGetPeriod.

Determines the validity and sample type of a WAVEFORMATEX structure

Parameters:

	pwfx	The structure to examine
[out]	pIsFloat	If the function returns nonzero, this is set to nonzero if the structure describes a format with float samples, zero otherwise.

Returns:: Nonzero if the WAVEFORMATEX struct has a WAVE_FORMAT_EXTENSIBLE type

BOOL IsSSE2Supported ( )

Deterines whether SSE2 support is present

void SetCurrentThreadName ( const char * pszThreadName )

Sets the name if the current thread in the Visual Studio debugger

As an exception is used to set the name, the entire thing is wrapped around an IsDebuggerPresent() check.

Parameters:

pszThreadName The name of the current thread
