import ( "github.com/calmh/xdr" "os" ) func main() { f, _ := os.Open("myfile.xdr") defer f.Close() xrdr := xdr.NewReader(f) myString, err := xrdr.ReadStringMax(100) // Read a string of up to 100 bytes if err != nil { // Handle error } else { // Use myString } }In this example, the code imports the calmh/xdr package, and then opens a file for reading. It creates a new xdr.Reader instance, passing the opened file as an argument. Then, it reads a string from the file using the ReadStringMax() method of the reader, with a maximum length of 100 bytes. If the reading is successful, the resulting string is stored in the myString variable for further processing. This example demonstrates how to use the calmh.xdr package to read strings from XDR-formatted data streams.
