WebMar 1, 2024 · What you can do is to create a Fortran function, which just calls the C wrapper for MPI_Comm_f2c and than call your C function in Fortran using a bind (C) interface as status = CFunction (something, c_comm) and thus avoid creating a wrapper for each C function. You just need a Fortran interface block for them. WebFortran技术规范ISO/IEC TS 29113:2012关于Fortran与C的进一步互操作性，允许Fortran具有此功能。在Fortran 2008下，这是不可能的。目前仍有一些编译器不支持此功能。使用这些编译器，仍有一个（尽管需要更多的工作）能够支持“可选”参数. 问题的过程 foo
