Run-Time Subroutine: Initializes the Fortran run-time environment. It establishes handlers and floating-point exception handling, so Fortran subroutines behave the same as when called from a Fortran main program.
This routine should be called from a C main program; it is invoked by default from a Fortran main program.
Syntax
To clean up the Fortran run-time environment, use FOR_RTL_FINISH_.
Example
Consider the following C code:
int argc;
char **argv;
void for_rtl_init_ (int *, char **);
for_rtl_init_ (&argc, argv);
