This patch series adds proper error checking to functions such as write(), ftruncate(), and system(), whose return values were previously ignored. These warnings were treated as errors under -Werror due to the __attribute__((warn_unused_result)) annotation. Instead of suppressing them with compiler flags, this series addresses each call site directly to improve code robustness and clarity. A full list of compiler warnings fixed in this series is available at: https://gist.github.com/EricccTaiwan/a78d6f1950d3cba27be757e405b6626a Tested on Ubuntu 25.04 (GCC 14.2.0, glibc 2.41).
