Abstract: Methods, media and systems that use an encoded opaque pointer in an API between a client process and a library process. An encoded opaque pointer, in one embodiment, can be received by the library process from the client process, and the library process can decode the opaque pointer to obtain an address in memory containing a data structure pointed to by the opaque pointer. The library process can operate on the data structure to create a revised or processed data structure, stored in the same or different address in heap memory or stack memory, and the library process can encode and return a new opaque pointer, for the processed data structure, to the client process.
