The specification for syslog() is void syslog(int priority, const char *format, ...); and your call uses buf as the format parameter, but its content does not contain any format control characters, and your call does not include any parameters. If you rewrite it as syslog(level, "%s", buf); it should work OK. Just say 'NO' to evaluated arguments for diadic functions! Ash

You're welcome. If you get bored some dark night you might want to read some of the documentation on g++, I think g++ --help gives you quite a lot of information. Just say 'NO' to evaluated arguments for diadic functions! Ash

thank you.

This is called 'generic' programming. The term 'generic' means that the definition of the for_each function does not assume anything else from the template argument than that it has an operator()( T ). If they would have implemented it using a function pointer, # they would have needed to specify the function pointer's type (e.g. void (*) (int)) and thus would have disallowed any other type of function (remember C) # they would have disallowed the use of stateful functions (e.g. accumulators), like often needed for the algorithms Also, the usage of templates greatly improves the optimizer's chances: it knows _at compile time_ what the body of the for_each block is going to be, so it can often skip parameter pushing etc..., hence reducing function call overhead.

printf("%d",a ); //can get 49 This line says print the decimal value of variable a; since a contains the character '1' it prints the ASCII value, which is 0x31 or 49 decomal. printf("%c",a ); //can get 1 This says print the character stored in variable a, which is the character '1'.

thank you very much, i will condsider

it sounds like you want to convert the php scripts to an executable. Besides doing a lot of coding by hand, I can only think of one application that may help you and it is called "hip hop". It is used by facebook to covert their php scripts to compiled executables to improve the performance. I am not sure how the cacti license is set up so your on you own there. http://developers.facebook.com/blog/post/358[^]

You're welcome. :thumbsup: Just say 'NO' to evaluated arguments for diadic functions! Ash

Please Give us stl_tempbuf.h

thanks, I'll have a look when I get a moment. Cheers, Ash

thank you very much.

You have set the dwNumberOfBytesToMap parameter for the destination file to 0. Memory mapped files cannot grow like a disk files. You have to create the destination file with blanks and set the dwNumberOfBytesToMap to the desired number of bytes. To create a blank file use SetEndOfFile after the CreateFile call. «_Superman_» I love work. It gives me something to do between weekends.
