Always cast pread, lseek etc. offsets to off_t.#1442
Merged
Conversation
When calling libc functions that take `off_t` arguments, always cast to `off_t`. On platforms where this cast is a no-op, these casts should be optimized away. This eliminates the need for explicit `cfg`s for platforms which need the casts. Fixes #1432.
