[SqueakDBX] Re: ideas for Smalltak GSoC 2011

[Mariano Martinez Peck]

Ok....after loading the Parcel OracleEXDI  and browsing the class
OracleInterface, I can guess they use FFI to talk to OCI.

Example:

OCIBindByName: stmtp with: bindp with: errhp with: placeholder with:
placeh_len with: valuep with: value_sz with: dty with: indp with: alenp
with: rcodep with: maxarr_len with: curelep with: mode
    <C: sword OCIBindByName(OCIStmt * stmtp, OCIBind * * bindp, OCIError *
errhp, const OraText * placeholder, sb4 placeh_len, void * valuep, sb4
value_sz, ub2 dty, void * indp, ub2 * alenp, ub2 * rcodep, ub4 maxarr_len,
ub4 * curelep, ub4 mode)>
    ^self externalAccessFailedWith: _errorCode


Cheers

Mariano
