<div class="markdown_content"><p>In the memory library is a function "compare".<br/> This uses 2 pointers to memory blocks.<br/> If the result is 0, they are the same, otherwise the return value refers to the first byte where the difference is.</p></div>

<div class="markdown_content"><p><em>Originally created by:</em> scott_cunningham</p> <p>You use pointers and compare each byte of the first with the second. See BUFFER_COMP in the OSCAT library for a free, already existing function. Otherwise you can make your own. SIZEOF() will tell you how many bytes to compare.</p></div>

<div class="markdown_content"><p>Hi,</p> <p>How can we compare two structures between them? <br/> I mean compare values of structure 1 members EQUAL to values of structure 2 members, like IF STRUCTURE 1 = STRUCTURE 2 THEN....</p> <p>Thank you.<br/> Best regards,<br/> Zdenko.</p></div>
