I have to insist: I have VERY good reasons to not tell Cython/Pyrex that the opaque type is an int. Instead, I REALLY need to tell that they are pointers, and not just a typedef to void*, but to DIFFERENT, INCOMPATIBLE, fake structures. Why am I being so pedantic about this? Because if I tell Cython/Pyrex that various MPI opaque types are 'int', and the underlying MPI implementation also uses 'int' for defining (using typedef's ) the various different handle types, then I do not have ANY guard against mistakes (I mean, like passing a actual int instead of MPI_Comm in some call). Greg, please tell me, what could go wrong with accepting external definition for except clauses? I cannot imagine any potential issue, but your "resistance" to my use case makes my think that you have some concerns about my request... -- Lisandro Dalcín --------------- Centro Internacional de Métodos Computacionales en Ingeniería (CIMEC) Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) PTLC - Güemes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594 _______________________________________________ Cython-dev mailing list [email protected] http://codespeak.net/mailman/listinfo/cython-dev
