How to Filter Out Broken Pipe Errors in Network Connections?

Filtering Out Broken Pipe Errors

When dealing with network connections, it's common to encounter broken pipe errors when the connection is prematurely terminated. To differentiate broken pipe errors from other types of errors, it's essential to inspect the error interface returned by I/O operations.

The broken pipe error is defined as syscall.EPIPE within the syscall package. To filter out broken pipe errors, you can compare the error with syscall.EPIPE using the equality operator:

<code class="go">if err == syscall.EPIPE {
    // Handle broken pipe error
}</code>

This approach allows you to explicitly handle broken pipe errors while ignoring other types of errors that may arise during I/O operations. It's important to note that if you need to obtain the actual error number, you can use a type assertion as follows:

<code class="go">if e, ok := err.(syscall.Errno); ok {
    errno = uintptr(e)
}</code>
