In Zephyr, _POSIX_THREAD_SAFE_FUNCTIONS is defined when any of CONFIG_POSIX_C_LANG_SUPPORT_R, CONFIG_POSIX_FILE_SYSTEM_R, CONFIG_POSIX_FILE_LOCKING, or CONFIG_POSIX_SYSTEM_DATABASE_R is enabled.

_POSIX_THREAD_SAFE_FUNCTIONS

Note

_POSIX_THREAD_SAFE_FUNCTIONS is advertised when any one of the Kconfig options above is enabled, even when the others are not. For example, an application that enables only CONFIG_POSIX_C_LANG_SUPPORT_R sees the macro defined while readdir_r() (from POSIX_FILE_SYSTEM_R) and flockfile() (from CONFIG_POSIX_FILE_LOCKING) are unavailable. Strictly conformant applications should enable all four Kconfig options.
