globals in C

[deb9]

Hi,

I have the following code

void (*somevector[20])(someptr *ptr);

void foo(someptr * ptr){...}

void somefunction() {
do something with somevector[0];
}

void otherfunction() {
somevector[0]=foo;
somefunction();
}

It keeps telling me in somefunction that somevector[0] is null, even if I initialize it in otherfunction. What is the problem? Isnt somevector global anyway?

Thanks

Show us the code in somefunction.
There is a suspicious pointer to pointer (?) parameter someptr* ptr).
Yes, you have a global array of pointers to functions. Of course, you have an initialization of its 1st element...
