Function PHYSFS_openRead 

pub unsafe extern "C" fn PHYSFS_openRead(
    filename: *const c_char,
) -> *mut PHYSFS_File

\fn PHYSFS_File *PHYSFS_openRead(const char *filename) \brief Open a file for reading.

Open a file for reading, in platform-independent notation. The search path is checked one at a time until a matching file is found, in which case an abstract filehandle is associated with it, and reading may be done. The reading offset is set to the first byte of the file.

Note that entries that are symlinks are ignored if PHYSFS_permitSymbolicLinks(1) hasn’t been called, and opening a symlink with this function will fail in such a case.

\param filename File to open. \return A valid PhysicsFS filehandle on success, NULL on error. Use PHYSFS_getLastErrorCode() to obtain the specific error.
