16 /* For the record: with SYSLOG_NAMES <syslog.h> defines

23 /*const*/ CODE prioritynames[] = {
24 { "alert", LOG_ALERT },
28 /* same for facilitynames[] */
30 /* This MUST occur only once per entire executable,
31 * therefore we can't just do it in syslogd.c and logger.c -
32 * there will be two copies of it.
34 * We cannot even do it in separate file and then just reference
35 * prioritynames[] from syslogd.c and logger.c - bare <syslog.h>
36 * will not emit extern decls for prioritynames[]! Attempts to
37 * emit "matching" struct _code declaration defeat the whole purpose
40 * For now, syslogd.c and logger.c are simply compiled into
45 /* musl decided to be funny and it implements these as giant defines
46 * of the form: ((CODE *)(const CODE []){ ... })
47 * Which works, but causes _every_ function using them
48 * to have a copy on stack (at least with gcc-6.3.0).
49 * If we reference them just once, this saves 150 bytes.
50 * The pointers themselves are optimized out
51 * (no size change on uclibc).
