DebugLib:
Fix a bug in PeiDxeDebugLibReportStatusCode: it should use gReportStatusCodeDebugType so that report status code infrastructure can correctly extract debug info. Fix functional and coding style issues in the three instances in EdkModulePkg, namely: EdkDxeDebugLibReportStatusCode, EdkUefiDebugLibStderr, EdkUefiDebugLibConout. DevicePathLib: Sync with MWG 0.57 and add new interface of CreateDevicePathNode(). All the function headers have been updated. PeiServicesLib: Adjust coding style and fix a minor comment error. PciLib: Adjust assert() condition to sync with MWG 0.57 BaseMemoryLib: Adjust assert() for ScanMemXX (), ScanGuid() Rename UefiMemoryLib to DxeMemoryLib PrintLib: Change the return value of all print services to exclude the NULL-terminator. Misc: Slightly adjust the coding style in hob.c in PeiCore module. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@758 6f19259b-4bc3-4df7-8a09-765794883524

/**
|

Scans a target buffer for a 64-bit value, and returns a pointer to the matching 64-bit value
|

in the target buffer.
|
||||
|
||||
This function searches target the buffer specified by Buffer and Length from the lowest
|
||||
address to the highest address for a 64-bit value that matches Value. If a match is found,
|
||||
then a pointer to the matching byte in the target buffer is returned. If no match is found,
|
||||
then NULL is returned. If Length is 0, then NULL is returned.
|
||||
If Length > 0 and Buffer is NULL, then ASSERT().
|
||||
If Buffer is not aligned on a 64-bit boundary, then ASSERT().
|
||||
If Length is greater than (MAX_ADDRESS <20> Buffer + 1), then ASSERT().
|
||||
|

@param Buffer Pointer to the target buffer to scan.

@param Length Number of bytes in Buffer to scan.

@param Value Value to search for in the target buffer.

@return A pointer to the matching byte in the target buffer or NULL otherwise.
