|- Generate messages for all routines/macros without a Fortran counterpart.|
|- Directory for output file|
|- file that contains common includes|
|- translate pointers to integer indices|
|- prefix for names of functions to convert to/from pointers (default is __). The macro that selects the form based on the pointer size can be changed with -ptr64.|
|- Generate a single Fortran wrapper that works for almost all systems, by adding C preprocessor names (see below). These names can be changed with -fcaps, -fuscore, and -fduscore.|
|- Fortran versions return the value of the routine as the last argument (an integer). This is used in MPI and is a not uncommon approach for handling error returns.|
|- Handle MPI datatypes (some things are pointers by definition)|
|- Handle MPI datatypes using MPI2 converstion functions (some things are pointers by definition)|
|- Do not generate PMPI names|
|- Change macro used to select MPI profiling version|
|- Turn off the generation of the profiling version|
|- Multiple indirects are native datatypes (no coercion)|
|- Consider "void *" as a pointer to a structure.|

- Generate ANSI-C style headers instead of Fortran interfaces
This will be useful for creating ANSI prototypes without ANSI-fying the
code. These use a trick to provide both ANSI and non-ANSI prototypes.
The declarations are wrapped in "ANSI_ARGS", the definition of which
#ifdef ANSI_ARG #undef ANSI_ARG #endif #ifdef __STDC__ #define ANSI_ARGS(a) a #else #define ANSI_ARGS(a) () #endif
- Do not add
#ifndef DEBUG_ALL #define DEBUG_ALL #endif
to the wrapper file.
- Generate a single wrapper that can handle the three most common
cases: trailing underscore, no underscore, and all caps. The
choice is based on whether
FORTRANCAPS: Names are uppercase, no trailing underscore FORTRANUNDERSCORE: Names are lowercase, trailing underscore are defined. FORTRANDOUBLEUNDERSCORE: Names are lowercase, with TWO trailing
underscores. This is needed when some versions of "f2c" are used to generate C for Fortran routines. Note that f2c uses two underscores ONLY when the name already contains an underscore (at least on the FreeBSD system that I use that uses f2c). To handle this case, the generated code contains the second underscore only when the name already contains one.
If -mapptr is also chosen, then
will also be used to determine if pointers are to long to fit in a 32-bit Fortran integer. Routines that destroy a pointer will need to manually insert a call to __RmPointer. The routines for managing the pointers are in ptrcvt.c
In addition, if -mpi is used and -no_pmpi is not, the MPI profiling names are also generated, surrounded by MPI_BUILD_PROFILING.
We really need a way to specify a general type as a pointer, so that it will be handled as a pointer. The -mpi option is a kludge for a pressing need. Eventually should provide a "-ptr name" option and keep in a search space when looking for known types.
