Approaches 2 and 3 provide type checking for most PETSc function calls; 4 has type checking 2348 for only a few PETSc functions. 2349 2350 Fortran type checking with interfaces is strick, this means you cannot pass a scalar value when an array value 2351 is expected (even though it is legal Fortran). For example when setting a single value in a matrix with MatSetValues() 2352 you cannot have something like 2353 $ PetscInt row,col 2354 $ PetscScalar val 2355 $ ... 2356 $ call MatSetValues(mat,1,row,1,col,val,INSERT_VALUES,ierr) 2357 You must instead have 2358 $ PetscInt row(1),col(1) 2359 $ PetscScalar val(1) 2360 $ ... 2361 $ call MatSetValues(mat,1,row,1,col,val,INSERT_VALUES,ierr) 2362 2363 2364 See the example src/vec/vec/examples/tutorials/ex20f90.F90 for an example that can use all four approaches 2365 2366 Developer Notes: The petsc-finclude/petscXXXdef.h contain all the #defines (would be typedefs in C code) these 2367 automatically include their predecessors; for example petsc-finclude/petscvecdef.h includes petsc-finclude/petscisdef.h 2368 2369 The petsc-finclude/petscXXXX.h contain all the parameter statements for that package. These automatically include 2370 their petsc-finclude/petscXXXdef.h file but DO NOT automatically include their predecessors; for example 2371 petsc-finclude/petscvec.h does NOT automatically include petsc-finclude/petscis.h 2372 2373 The petsc-finclude/ftn-custom/petscXXXdef.h90 are not intended to be used directly in code, they define the 2374 Fortran data type type(XXX) (for example type(Vec)) when PETSc is ./configure with the --with-fortran-datatypes option. 2375 2376 The petsc-finclude/ftn-custom/petscXXX.h90 (not included directly by code) contain interface definitions for 2377 the PETSc Fortran stubs that have different bindings then their C version (for example VecGetArrayF90). 2378 2379 The petsc-finclude/ftn-auto/petscXXX.h90 (not included directly by code) contain interface definitions generated 2380 automatically by "make allfortranstubs". 2381 2382 The petsc-finclude/petscXXX.h90 includes the custom petsc-finclude/ftn-custom/petscXXX.h90 and if ./configure 2383 was run with --with-fortran-interfaces it also includes the petsc-finclude/ftn-auto/petscXXX.h90 These DO NOT automatically 2384 include their predecessors 2385 2386 Level: beginner 2387 2388 M*/ 2389 2390 PETSC_EXTERN PetscErrorCode PetscGetArchType(char[],size_t);
