C++ (Cpp) file_rotate Examples

Example #1

File: util.c Project: jonasbits/bitc

void
Log_Init(const char *filename)
{
   time_t ltime;

   if (!filename) {
      return;
   }

   if (file_exists(filename)) {
      file_rotate(filename, 10);
   }

   logState.lock = mutex_alloc();
   logState.f = fopen(filename, "a");
   if (logState.f == NULL) {
      printf(LGPFX" Failed to create log file '%s'\n", filename);
   }
   file_chmod(filename, 0600);
   strncpy(logState.filePath, filename, sizeof logState.filePath);

   ltime = time(NULL);

   LogAlways(LGPFX" new log session: %s", asctime(localtime(&ltime)));
}
