Steve,
Thanks. i will start working on moving towards CPG API usage.
the current code which has been working with us needs to be maintained for
sometime. for that i am working on modifying it.
for time being it would be helpful if following two are clarified.
1) purpose of handle db: i am assuming hdb_handle_create() /
handle_destroy() apis will allocate/ free memory of size (2nd param of
create() api). my library is very simple and links into an app. i can
maintain the handles in handle_t varaibles.. why handle database should
be used? is it to maintain large runtime structures and reference them
with these handles? i dont want any memory allocation in hdb handle
database for my data. and my library is doesnt have to support multi
threaded application
2) if a service engine writes a structure twice in an ipc dispatch
buffer...(using ipc_dispatch_send() ) ....and inside lib when i read
using coroipcc_dispatch_get()..will both messages be be read into void**
param? ..i didnt get the pinning concept from documentation
Thanks
Ramesh
