bfort(1) bfort(1) NAME bfort - program to extract short definitions for a Fortran to C interface INPUT filenames - Names the files from which lint definitions are to be extracted -nomsgs - Do not generate messages for routines that can not be converted to Fortran. -nofort - Generate messages for all routines/macros without a Fortran coun- terpart. -dir name - Directory for output file -I name - file that contains common includes -mapptr - translate pointers to integer indices -ptrprefix - 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. -anyname - Generate a single Fortran wrapper that works for almost all sys- tems, by adding C preprocessor names (see below). These names can be changed with -fcaps, -fuscore, and -fduscore. -ferr - Fortran versions return the value of the routine as the last argu- ment (an integer). This is used in MPI and is a not uncommon ap- proach for handling error returns. -mpi - Handle MPI datatypes (some things are pointers by definition) -mpi2 - Handle MPI datatypes using MPI2 converstion functions (some things are pointers by definition) -no_pmpi - Do not generate PMPI names -pmpi name - Change macro used to select MPI profiling version -noprofile - Turn off the generation of the profiling version -mnative - Multiple indirects are native datatypes (no coercion) -voidisptr - Consider "void *" as a pointer to a structure. -ansi - C routines use ANSI prototype form rather than K&R C form -ansiheader - 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 proto- types. The declarations are wrapped in "ANSI_ARGS", the definition of which should be #ifdef ANSI_ARG #undef ANSI_ARG #endif #ifdef __STDC__ #define ANSI_ARGS(a) a #else #define ANSI_ARGS(a) () #endif -nodebug - Do not add #ifndef DEBUG_ALL #define DEBUG_ALL #endif to the wrapper file. -anyname - 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 al- ready contains one. If -mapptr is also chosen, then POINTER_64_BITS 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. NOTE 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. AUTHOR Bill Gropp LOCATION bfort.c 1/5/2000 bfort(1)
