I’m adding code to create new logs files periodically. This is on winnt. Since none of the log file support is thread safe, I want to add an access lock. I can’t seem to get apr_thread_mutex_t defined in httpd.h. I’ve added #include “apr_thead_mutex.h” to no avail, there’s some dependency I can’t quite see. Any of you experts know the magic incantation?
That should do the trick. What do you do to make sure your build system can find that header? I have an example module, mod_example_ipc.c, that uses global mutexes. It doesn't explicitly include any APR mutex header, but I seem to be so lucky as to pick it up automatically:
#include "apr.h" #include "apr_strings.h" #include "httpd.h" #include "http_config.h" #include "http_log.h" #include "http_protocol.h" #include "ap_config.h"#if !defined(OS2) && !defined(WIN32) && !defined(BEOS) && !defined (NETWARE)
#include "unixd.h"#define MOD_EXIPC_SET_MUTEX_PERMS /* XXX Apache should define something */
#endif #if APR_HAVE_SYS_TYPES_H #include <sys/types.h> #endif #if APR_HAVE_UNISTD_H #include <unistd.h> #endif For more details, see http://www.temme.net/sander/mod_example_ipc/ S. -- sctemme@xxxxxxxxxx http://www.temme.net/sander/ PGP FP: 51B4 8727 466A 0BC3 69F4 B7B8 B2BE BC40 1529 24AF
