I am trying to pass a typedef struct pointer to a function and the compiler is complaining with this error message: error: unknown type name ‘RootP’. Here is the code...
int main()
{
typedef struct Root
{
struct Root *child;
}*RootP;
RootP rootNode = malloc(sizeof(struct Root));
rootNode->child = NULL;
....
}
void mkdir(RootP rootNode, char param2[60], char pwd[200])
{
...
}
The struct should be outside of main, so move
typedef struct Root
{
struct Root *child;
}*RootP;
before the main function. If the program is big enough, consider moving that into some header file (*.h)
And I would avoid using the mkdir name. It is defined in Posix and on Linux refers to the mkdir(2) system call.
I don't feel that typedef struct Root *RootP; is pretty code: you usually want to see at a glance what C thing is a pointer. I would instead declare the struct root_st and have typedef struct root_st Root; (Gtk also uses that, or a very similar, coding convention). And code Root* rootnode. But it is debatable and a matter of taste.
mymkdir; it is making your code confusing.mkdir name and link with a library calling mkdir (and a lot of C libraries might do that) you'll have big, hard to hunt, bugs.
