◆ DebugLibFdtPL011UartWrite()

UINTN DebugLibFdtPL011UartWrite	(	IN UINT8 *	Buffer,
		IN UINTN	NumberOfBytes
	)

(Copied from SerialPortWrite() in "MdePkg/Include/Library/SerialPortLib.h" at commit c4547aefb3d0, with the Buffer non-nullity assertion removed:)

Write data from buffer to serial device.

Writes NumberOfBytes data bytes from Buffer to the serial device. The number of bytes actually written to the serial device is returned. If the return value is less than NumberOfBytes, then the write operation failed. If NumberOfBytes is zero, then return 0.

Parameters

Buffer	Pointer to the data buffer to be written.
NumberOfBytes	Number of bytes to written to the serial device.

Return values

0	NumberOfBytes is 0.
>0	The number of bytes written to the serial device. If this value is less than NumberOfBytes, then the write operation failed.
