FORTRAN function returning an array causes a segfault (calling from C++)
- by Dane Larsen
Basically, here's my problem. I'm calling someone else's FORTRAN functions from my C++ code, and it's giving me headaches. Some code:
function c_error_message()
character(len = 255) :: c_error_message
errmsg(1:9) = 'ERROR MSG'
return
end
That's the FORTRAN function. My first question is: Is there anything in there that would cause a segfault?
If not, then second: What does that return? A pointer?
I'm trying to call it with the following C statement:
char *e = c_error_message_();
That causes a segfault.
c_error_message();
That too causes a segfault.
I declared c_error_message_() earlier on with the following code:
extern"C" {
char* c_error_message_();
}
Would declaring a function with a different return type than the actual return type cause a segfault?
I'm at a loss. Thanks for any replies.
