MVIbp_Sleep
Syntax:
int MVIbp_Sleep( MVIHANDLE handle, WORD msdelay );
Parameters:
handle handle returned by previous call to MVIbp_Open
msdelay time in milliseconds to suspend task
Description:
MVIbp_Sleep suspends the calling thread for at least msdelay
milliseconds. The actual delay may be several milliseconds longer than
msdelay , due to system overhead and the system timer granularity
(5ms).
Return Value:
MVI_SUCCESS success
MVI_ERR_NOACCESS
handle does not have access
Example:
MVIHANDLE handle;
int timeout=200;
// Simple timeout loop
while(timeout--)
{
// Poll for data, etc.
// Break if condition is met (no timeout)
// Else sleep a bit and try again
MVIbp_Sleep(10);
}
