expected declaration specifiers or ‘...’ before ‘FILE’

I am writing code in c.
I am declaring a FILE* fp at the main function (main.c).
We have other files at the project too.
So at a header file I am getting this error:
"expected declaration specifiers or ‘...’ before ‘FILE’ problem"
at this line:
void myfunct(argumenttype argument, FILE *fp);

What am I doing wrong?

Working in Linux(gedit+gcc).

argumenttype is a typedef'ed type of pointer to a struct.

typedef struct testStruct testptr;
void myfunct(testptr test, FILE *fp);

I have just included stdio.h at this header file. And it worked fine. So everywhere I use library dependant functions or typedef'ed types I must include the relevant library?

Thank you very much!

You must include the header before you use the typedef'd element, otherwise FILE means nothing to the compiler, and it doesn't know what it is looking at.
