lpdwNumberOfBytesSent

lpdwNumberOfBytesSent is a parameter commonly used in networking and data transmission contexts to represent the number of bytes that have been successfully sent over a network connection or communication interface. It typically appears as a variable or parameter within API functions, system calls, or network programming environments, serving as a means to track or specify data transfer quantities.

In most implementations, lpdwNumberOfBytesSent is a pointer to a variable of type DWORD (a 32-bit unsigned integer), which receives the count of bytes sent during a particular data transmission operation. For example, in Windows networking APIs such as WSASend or WSASend, this parameter helps determine how many bytes were successfully transmitted, enabling developers to handle partial sends or retransmission strategies effectively.

Accurate usage of lpdwNumberOfBytesSent is crucial for ensuring data integrity and managing network resources efficiently. It is often used in conjunction with other parameters to facilitate non-blocking or asynchronous communication, allowing applications to monitor the progress of data transfers and respond accordingly.

Given its role in low-level network programming, understanding the context and proper handling of lpdwNumberOfBytesSent is essential for developers working on network applications, especially those involving robust data exchange, streaming, or real-time communication systems. Proper error checking and handling of the value stored in lpdwNumberOfBytesSent are vital to ensure reliable and predictable network operations.
