cntNPOpen

cntNPOpen is a function commonly found in programming libraries or operating system interfaces that relates to network operations. Its name suggests it is used to open a network connection or resource. The "cnt" prefix might indicate it's part of a specific library or module, possibly related to networking control or connectivity. The "NPOpen" part likely signifies "Network Port Open" or "Network Path Open," implying the establishment of a communication channel.

When cntNPOpen is called, it typically takes parameters that define the target network address, port number, and potentially protocol type (e.g., TCP or UDP). The function then attempts to establish a connection to the specified network endpoint. If successful, it usually returns a handle or identifier that can be used for subsequent data transmission and reception. Conversely, if the connection cannot be established due to network issues, incorrect parameters, or the target service not being available, the function would likely return an error code or a null value. This function is a fundamental building block for any application that needs to communicate over a network.
