* Minimal replacement for wpa_supplicant's src/utils/common.h + the parts
|
|
* of src/utils/os.h that wpa_ctrl.c (CONFIG_CTRL_IFACE_UNIX build path)
|
|
* actually needs. Trivial os_* helpers are mapped directly onto libc via
|
|
* macros (matching upstream's own os.h fallback definitions); the handful
|
|
* that need a real body (os_zalloc, os_strlcpy, os_get_reltime, os_sleep)
|
|
* are implemented in jl_wpa_os_shim.c.
