memmem() Function for a C Program

March 17, 2020 Roger Lacroix

Last week, I needed a function for a C program that would search a string not null terminated for a string not null terminated.

Java’s Missing Byte Array Class

February 19, 2020 Roger Lacroix

After 25 years, it is still surprising that Java doesn’t have a proper byte array class. There can be many reasons that the data a Java program needs to work with is in a byte array. It could be the contents of a file or MQTT message or IBM MQ message, etc. Since there is […]

Sometimes people over think a problem and write a complicated solution when really the solution is no different than any other Request/Reply scenario (use case). On StackOverflow, someone asked a question about sending a reply JMS/MQRFH2 message using the RFH2 header and folder values from the original request message. The code will copy the RFH2 […]
