Activation – Callback API Activation. Macros#define GLOBUS_CALLOUT_MODULE Variablesglobus_module_descriptor_t globus_i_callout_module Detailed DescriptionCallback API Activation. Globus Callout API uses standard Globus module activation and deactivation. Before any Globus Callout API functions are called, the following function must be called: * globus_module_activate(GLOBUS_CALLOUT_MODULE) * This function returns GLOBUS_SUCCESS if Globus Callout API was successfully initialized, and you are therefore…
