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
CALL for_rtl_init_ (argcount, actarg)
argcount
Is a command-line parameter describing the argument count.
actarg
Is a command-line parameter describing the actual arguments.
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);
