I am still confused then.
Why having AP_DECLARE(void) ap_log_perror_ then?
Why define ap_log_perror to ap_log_perror_ on non C99 compilers then?
ap_do_log_perror only shows up in the definition of ap_log_perror__
nowhere else.
What does it do?
It allows (with C99 compilers) to remove debug/trace logging at compile
time by defining APLOG_MAX_LOGLEVEL. The other ap_log_*error functions
allow the same.
Sorry for be a PITN, but if APLOG_MAX_LOGLEVEL is defined on a C99 environment
this results is the following:
