Apparatus, system, and method for executing functions in an event driven environment from a co-routine environment

A computer program product comprising a computer useable medium having a computer readable program, wherein the computer readable program when executed on a computer causes the computer to:

• store parameters and a proxy function pointer for a proxy function in a bridge structure while executing a second context in a second environment, the proxy function configured to execute in a first environment;
• store a bridge pointer for the bridge structure in a bridge pointer register of a first context structure that stores a first context state for a first context configured to execute in the first environment;
• swap to the first context;
• retrieve the proxy function pointer from the bridge structure using the bridge pointer if the bridge pointer register is not null;
• execute the proxy function;
• store the results of the proxy function in the bridge structure;
• and
• swap to the second context.

A system to execute a function in an event driven environment from a co-routine environment, the system comprising:

• a processor module configured to execute software processes;
• a memory module configured to store the software processes, the software processes comprising
• a context structure module configured to create an event driven context structure and a co-routine context structure;
• a bridge module configured to store parameters and a proxy function pointer for a proxy function in a bridge structure for a co-routine context executing in the co-routine environment, the proxy function configured to execute in the event driven environment, and to store a bridge pointer for the bridge structure in a bridge pointer register of the event driven context structure that stores an event driven context state for an event driven context configured to execute in the event driven environment;
• a swap context module configured to swap to the event driven context;
• an execute module configured to retrieve the proxy function pointer from the bridge structure using the bridge pointer if the bridge pointer register is not null, execute the proxy function, and store the results of the proxy function in the bridge structure;
• and
• the swap context module further configured to swap to the co-routine context.

A method for deploying computer infrastructure, comprising integrating computer-readable code into a computing system, wherein the code in combination with the computing system is capable of performing the following:

• creating an event driven context structure and a co-routine context structure;
• storing parameters and a proxy function pointer for a proxy function in a bridge structure while executing a co-routine context in a co-routine environment, the proxy function configured to execute in an event driven environment;
• storing a bridge pointer for the bridge structure in a bridge pointer register of the event driven context structure that stores an event driven context state for an event driven context configured to execute in the event driven environment;
• swapping to the event driven context;
• retrieving the proxy function pointer from the bridge structure using the bridge pointer if the bridge pointer register is not null;
• executing the proxy function;
• storing the results of the proxy function in the bridge structure;
• and
• swapping to the co-routine context.
