Flint can output a text file, in a pseudo-FORTRAN, which contains interface descriptions of all the routines that it has encountered in this run. The format is:
flint -o file ....Each routine in the output file will probably contain many `INTENT' statements (part of the FORTRAN-8X standard). INTENT is used to indicate whether a subroutine argument is input to or output from a routine (or both), or whether this is unknown. Typically a routine description would look like:
subroutine example(arg1,arg2,arg3,arg4) real arg1,arg2 integer arg3,arg4 intent(in) arg1,arg3 intent(out) arg3,arg4 intent(unknown) arg2 endHere Flint believes arg1 is input, arg4 is output, and arg3 is both input and output. Flint could not determine whether arg2 was input or output.
The user can edit an interface file created by Flint, or create an entire interface description by hand.
Such an interface description file appears as normal FORTRAN to Flint, so it can be input to Flint (to teach Flint about a users standard routine interfaces) on subsequent uses of Flint. While these interface definitions could be input along with normal source files, preceding the interface file with the -l (library) switch has the advantage that the source of this file does not appear in the listing file. Warning messages generated by analyzing this file are also suppressed.
The following example generates a interface description file, library.dat, from source files routine1.for, routine2.for and routine3.for. The interface definition is then used in a subsequent Flint run on program.for.
flint -o library.dat routine1.for routine2.for routine3.for flint -l library.dat program.for
