Need help with C function/strings

Scrag · 12-11-2004, 09:03 PM

I need help writing a C function that will be passed an http path, and the function will remove the %20 for space that is commonly in the file/path name. For example, the web browser asks for a file called "Cool File.mpg", but http displays it as "Cool%20File.mpg", I need a function that extracts the %20 from the file name, and returns the path without the %20 in it.. I've done this with a single char but not a string, and Im not sure how to get this started.

THANKS

You might check the man page for strstr. If you can use something outside of the standard C library, abnd you are familiar with regular expressions, you might want to look at libpcre, which is a C library that can do Perl Compatible regular expressions. I've never used it before though, so I'm not sure if it can do what you want.

Cool! strstr() is what I need. Hhmmmm....I guess I need to loop through the string now and fugure out how to replace each instance of "%20" with "\ ". Any suggestions on how I should to this, or is there already a function in place to replace a certain string in a string?

Thanks again for the help!
