I have two questions about gcc/g77:
1) I'm using egcs based gcc and g77 (version egcs-2.91.66
19990314(egcs-1.1.2 release) (from FSF-g77 version 0.5.24-
19981002)) to compile C and Fortran77 on a Linux box with
kernel 2.2.7. Is there a possibility to inline some C-Functions in
the Fortran Code while linking the objects for a better
performance of the executable?
What statements or flags have to be used on the C and Fortran
side?
2) Is there a possibility to use C allocated memory in Fortran?
(e.g.: a C-subroutine do dptr = (double*)malloc(...*sizeof(double))
and I want to access this array out of Fortran without copying
all it's values via the parameter list of the subroutine)
Best regards
K.Breuer
