Calling the strftime() Function

Paul Murray — Fri, 02 Feb 2001 18:36:06 GMT

Dear Gurus,

I am currently trying to develop my C skills, but cannot work out how to do the following ....

I want to prefix all entries to a logfile with the current sysdate/time in the format of "[ddmmmyy:HHMM.ss]" - it appears that the strftime() function call will allow me to do this, but I have absolutely no idea on how to call it !!!

Can someone please show me the lines of code I would need to use.

(Sorry for being a C-learner !!)

Regards,
Paul.

Try something like this:

#include

struct tm *t;
char buf[80];

t = localtime( time(NULL) );
strftime( buf, 80, "[%d%m%y:%H%M.%S]", t );

This is straight from the time(), localtime(), and strftime() man pages.

I hope this helps.

Kenneth,

Many, many thanks for the assistance. Unfortunately, I am getting the following error ....

Error 212: "WriteLog.cpp", line 48 # Argument type 'tm *' does not match expected parameter type 'long *'

Thanks again,
Paul.
