I've been backing lately on the LAPACK bindings and there's something I don't understand . Sometimes the fortranname statement is prefixed with `w`, like in
fortranname w<prefix2c>dotc
Someone could tell me why the w is needed?
It's because on some platforms there are difficulties in calling Fortran functions (as opposed to subroutines) from C, so we need subroutine wrappers for the functions. You can find the w* subroutines implemented in some *.f file. Pauli
