Globus Callout API.
This API is intended to ease integration of configurable callouts into the Grid Community Toolkit and to provide a platform independent way of dealing with runtime loadable functions. It (hopefully) achieves this goal by providing the following functionality:
- It provides a function for reading callout configuration files. Files are assumed to have the following format:
- It provides a API function for registering callouts
- All callouts are assumed to have the function signature globus_result_t callout_func(va_list ap)
- It provides a function for calling a callout given an abstract type. If multiple callouts are defined for the same abstract type then all callouts for the abstract type will be called. Implementers should not rely on any correlation between the order of configuration and the order of invocation of callouts of the same abstract type.
Any program that uses Globus Callout functions must include the globus_callout.h header
