OpenBSD Major Update: FILE Object Structure Becomes Opaque
2025-07-21
OpenBSD recently underwent a significant system update making the internal structure of the FILE object in its standard input/output library opaque. This means programs can no longer directly access the internal structure of the FILE object. The change is far-reaching, affecting libc and many libraries that depend on it, including libcrypto, libtls, and libssl. To ease the transition, some helper symbols are temporarily retained but will be removed in the future. Developers are strongly encouraged to use a snapshot upgrade to avoid potential problems.
