00470    * Format a message to the thread-safe ACE logging mechanism.  Valid






00471    * options (prefixed by '%', as in printf format strings) include:






00472    *  - 'A': print an ACE_timer_t value (which could be either double






00473    *         or ACE_UINT32.)






00474    *  - 'a': abort the program at this point abruptly.






00475    *  - 'c': print a character






00476    *  - 'C': print a character string






00477    *  - 'i', 'd': print a decimal number






00478    *  - 'I': indent according to nesting depth (obtained from






00479    *         ACE_Trace::get_nesting_indent()).






00480    *  - 'e', 'E', 'f', 'F', 'g', 'G': print a double






00481    *  - 'l': print line number where an error occurred.






00482    *  - 'M': print the name of the priority of the message.






00483    *  - 'm': return the message corresponding to errno value, e.g., as






00484    *         done by strerror()






00485    *  - 'N': print file name where the error occurred.






00486    *  - 'n': print the name of the program (or "<unknown>" if not set)






00487    *  - 'o': print as an octal number






00488    *  - 'P': print out the current process id






00489    *  - 'p': print out the appropriate errno message from sys_errlist,






00490    *         e.g., as done by perror()






00491    *  - 'Q': print out the uint64 number






00492    *  - 'q': print out the int64 number






00493    *  - '@': print a void* pointer (in hexadecimal)






00494    *  - 'r': call the function pointed to by the corresponding argument






00495    *  - 'R': print return status






00496    *  - 'S': print out the appropriate _sys_siglist entry corresponding






00497    *         to var-argument.






00498    *  - 's': print out a character string






00499    *  - 'T': print timestamp in hour:minute:sec:usec format.






00500    *  - 'D': print timestamp in month/day/year hour:minute:sec:usec format.






00501    *  - 't': print thread id (1 if single-threaded)






00502    *  - 'u': print as unsigned int






00503    *  - 'w': prints a wide character






00504    *  - 'W': print a wide character string






00505    *  - 'x': print as a hex number






00506    *  - 'X': print as a hex number






00507    *  - 'z': print an ACE_OS::WChar character






00508    *  - 'Z': print an ACE_OS::WChar character string






00509    *  - '%': print out a single percent sign, '%'
