Cinterop can't find FILE type [ERROR]

Hi there! I’m trying to build Kotlin/Multiplatform library, and I’m somewhat stuck with its Kotlin/Native implementation because of this error:

Exception in thread "main" java.lang.Error: IdeaProjects\multifile\multifile-in-c\src\main\public\multifile.h:15:29: error: unknown type name 'FILE'

Here is my multifile.h:

#ifndef MULTIFILE_IN_C_MULTIFILE_H
#define MULTIFILE_IN_C_MULTIFILE_H

#include <stdio.h>
#include <stdbool.h>


typedef struct {
    long size;
    unsigned char* bytesPointer;
    bool eof;
} bytesArray;

extern long getFileSize(const char *filename);
extern bytesArray readBytes(FILE *fp, long startFrom, long howMuch);
extern long getFileSizeByPointer(FILE *fp);
extern void freeBytesArray(bytesArray* array);

#endif //MULTIFILE_IN_C_MULTIFILE_H

I’m novice in Kotlin/Native, but I see that C programming language is much easier than set up this. I’ll appreciate any help you give me here :new_moon_with_face:
