lpInBuffer

lpInBuffer is a pointer to a buffer that receives data from a serial port. It is a parameter used in Windows API functions related to serial communication, such as ReadFile. The buffer is allocated by the application and its size determines how much data can be read at once. The lpInBuffer parameter is typically used in conjunction with other parameters like lpNumberOfBytesRead, which indicates the actual number of bytes transferred into the buffer. Properly managing the size and content of lpInBuffer is crucial for efficient and error-free serial data handling.
