µC/MQTT-client compile-time configuration allows for enabling/disabling of available features. This gives it a variable memory footprint (RAM & ROM).
A template configuration file (mqtt-c_cfg.h) is included in the module package (see Directories and Files). This configuration should be copied into the application directory and included in the project. Here is the list of each configuration variables description and value. However, keep in mind that future releases of this module might include more configuration options.
Argument Checking Configuration
All API functions in μC/MQTT-client include code to validate arguments that are passed to it. Specifically, μC/MQTT-client checks to see if passed pointers are NULL, if arguments are within valid ranges, etc. The following constant configures additional argument checking.
