Synopsis
APIRET APIENTRY KernPerfSysTrace(ULONG major,ULONG minor,PVOID buf, ULONG size);
Parameters
- major (ULONG) - input
- Major number of Perf event
- minor (ULONG) - input
- Minor number of Perf event
- buf (PVOID) - input
- Buffer to be added to the Perf log
- size (ULONG) - input
- Size of the buffer
Comments
- Warning
- The buffer is assumed to be allocated on the task stack, not as a global variable or a VMAlloc'd memory area.
