5.8 WD_Sleep()

PURPOSE

$\bullet$ Delays execution for a specific duration of time.

PROTOTYPE

DWORD WD_Sleep(
    HANDLE hWD,
    WD_SLEEP *pSleep);

PARAMETERS

Name Type Input/Output

$\bullet$ hWD HANDLE Input

$\bullet$ pSleep WD_SLEEP*

$\gg$ dwMicroSeconds DWORD Input

$\gg$ dwOptions DWORD Input

Name	Type	Input/Output
$\bullet$ hWD	HANDLE	Input
$\bullet$ pSleep	WD_SLEEP*
$\gg$ dwMicroSeconds	DWORD	Input
$\gg$ dwOptions	DWORD	Input

DESCRIPTION

Name Description

hWD The handle to WinDriver's kernel-mode driver received from WD_Open() [5.2]

pSleep Pointer to a sleep information structure:

dwMicroSeconds Sleep time in microseconds - 1/1,000,000 of a second.

dwOptions A bit-mask, which can be set to either of the following:
$\bullet$ Zero (0) - Busy sleep (default)
OR:
$\bullet$ SLEEP_NON_BUSY - Delay execution without consuming CPU resources. (Not relevant for under 17,000 micro seconds. Less accurate than busy sleep).

Name	Description
hWD	The handle to WinDriver's kernel-mode driver received from `WD_Open()` [5.2]
pSleep	Pointer to a sleep information structure:
dwMicroSeconds	Sleep time in microseconds - 1/1,000,000 of a second.
dwOptions	A bit-mask, which can be set to either of the following: $\bullet$ Zero (0) - Busy sleep (default) OR: $\bullet$ SLEEP_NON_BUSY - Delay execution without consuming CPU resources. (Not relevant for under 17,000 micro seconds. Less accurate than busy sleep).

RETURN VALUE

Returns WD_STATUS_SUCCESS (0) on success, or an appropriate error code otherwise [A].

REMARKS

Example usage: to access slow response hardware.

EXAMPLE

WD_Sleep slp;

BZERO(slp);
slp.dwMicroSeconds = 200;
WD_Sleep(hWD, &slp);
