Thread: sscanf() question

I am using sscanf() to parse a line with the date contained within. The semantics of the line is as follows:

Code:

Date: Tues, February 24th 2009

Now for my code I have:

Code:

sscanf(dummy, "Date: %s\n", date);

But when I execute this instead of obtaining "Tues, February 24th 2009" I am only getting "Tues".
How would I go about fixing this issue. Thanks!

%s stops at a space.

Thank you once again tabstop A little reading on the ole man page after you pointed that out and I found a solution to the problem. One more quick question is relating to an error I am getting when I compile with the -pedantic open enabled:

Code:

      	if((pRet = popen("ps -el", "r")) == NULL) {
	            fprintf(stderr, "ERROR:  File pointer returned a Null value\n");
	            fprintf(stderr, "ERRNO = %s\n", strerror(errno));
	            exit(1);
	 }

http.c:275: warning: implicit declaration of function ‘popen’
http.c:275: warning: assignment makes pointer from integer without a cast

But I have the pret declared as a FILE * to hold the return value from popen?

You need to include the header that contains popen.

I double checked the manpage and double checked to make sure <stdio.h> is included but I am still receiving the warning

Is there a way then to stop receiving this warning or do I just have to disabled -pedantic and/or ignore?

You're apparently targeting POSIX-like systems, so you can tell your implementation that by defining the _XOPEN_SOURCE macro to a suitable value. I'd recommend 600, which means SuSv3. You'd probably want to do this via the command-line, along the lines of:

Code:

gcc -Wall -std=c99 -pedantic -D_XOPEN_SOURCE=600

For the older, but still-has-everything-you-need-probably SuSv2:

Code:

gcc -Wall -std=c89 -pedantic -D_XOPEN_SOURCE=500
