<div>
<div class="content wysiwyg-content">
char* tempTransMsg;<br />
&nbsp; &nbsp;tempTransMsg = (char*)malloc(len); &nbsp;This line returns a NULL pointer even though I have over 600mb of memory left. &nbsp;len is an unsigned int and is normaly about 750. &nbsp;This is not the only time malloc is used in this program and it worked the other times.<br />
Thankyou for your time.

Malloc assines a NULL pointer with tons of memory left.

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
