[Orclib-users] How to pass OCILIB connection to a function in C?

[<mod...@co...>]

Hello, If I'm using OCILIB in the main function, such as:

int main (void) 
{
    OCI_Connection *cn; 
    OCI_Statement  *st;
    ...
    OCI_Initialize(NULL, NULL, OCI_ENV_DEFAULT);
    OCI_EnableWarnings(TRUE); 
    cn = OCI_ConnectionCreate(...);
    st = OCI_StatementCreate(cn);
    ...
    my_function(...);
}


When I create a new function, my_function, how do I pass the existing OCILIB connection into my_function for use? I want to avoid opening a new connection in my_function if it is not necessary. 

For example, I'd like to pass *cn and *st above into my_function.
