Last time, I showed how to replace PHP's str_replace in C.
The previous code was only replacing one occurrence of substr which might be sufficient in most cases... but will not do the job when the pattern appears more than once within the original string.
This new piece of code will replace ALL occurrences of substring by the replacement pattern.
GTK+ offers a nice toolkit through the GDK library to make image manipulation quite easy.
This page will go through the process of modifying an image but putting another on on top as an overlay. In this example, we will be copying an MSN icon on top of a "busy" icon.
Another use case could be to watermark images.
And example on how to implement str_replace in C.
This implementation will only replace the value once. If the substring to replace is not found, a copy of the original string is returned.
If you are looking for a version that replace all occurrences of substring, please have a look at str_replace all matching pattern.
Text completion is quite a nifty feature to have on an interactive software, saves you loads of typing, helps you remember the exact spelling on one's email, lost urls (thanks firefox 3 for the regex based search :-) )....
This tutorial will explain through a code sample how to set it up.
Once upon a time, file size was capped to 2G because of 2^31 - 1 = 2G. Has such, open will fail on files bigger than 2G.
this tutorial will show how to get standard C to handle large file.
Linux provide a high level socket API that will allow programmer to easily connect to any TCP or UDP services.
In this tutorial, we will see how this works by implementing a simple HTTP client which will get request a web page given the hostname and the page name, then read the server answer and output the HTML content of the reply.
