Extension points

The version 2.0 of the library comes with clear API extension and customization points.

Tweak hardware signature generator

If the provided hardware signatures don’t behave well for your customers, or you want to change the default way the library generates the pc identifier you can have a look at the following section.

First of all be sure to read about the standard behavior of identify_pc() here:

• Customize hardware signature generators
  • Change the hardware identification strategy
  • Implement your own hardware signature generator

Change the hardware identification strategy

Included with the library there are three hardware identification strategies: IP_ADDRESS, STRATEGY_ETHERNET (mac address) and STRATEGY_DISK (partition serial number). If you want to change the preferred one:

• locate the file licensecc_properties.h` (usually in projects/<$project_name>/include/licensecc/<$project_name>

• you can change the order of the strategies in the following code block (the strategies will be tried in sequence until the first one succeeds):

#define LCC_BARE_TO_METAL_STRATEGIES { STRATEGY_ETHERNET, STRATEGY_ETHERNET, STRATEGY_NONE } #define LCC_VM_STRATEGIES { STRATEGY_ETHERNET, STRATEGY_NONE } #define LCC_LXC_STRATEGIES { STRATEGY_ETHERNET, STRATEGY_NONE } #define LCC_DOCKER_STRATEGIES { STRATEGY_NONE } #define LCC_CLOUD_STRATEGIES { STRATEGY_NONE }

Custom license locator

Your software struggle to find the license file ? you can implement your own way to find it. For instance if you want to download the license from a remote server, you could implement the logic here.
