What is the c++ standard ( non-windows) equivalent of Fuction SetFilePointer()

I have a function using SetFilePointer()

HANDLE In; SetFilePointer(In, 3, NULL, 0); 

I want to adapt this function for non-windows platforms taking a Pointer to FILE (FILE*) as argument .

What function Set_File_Pointer_SomeHow() does the same as SetFilePointer() which can I use for that?

FILE* In; Set_File_Pointer_SomeHow(In, );

I think you want std::fseek(std::FILE* stream, long offset, int origin).
