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

Question

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).

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.
