    Hi,

    How can we compare two structures between them?
    I mean compare values of structure 1 members EQUAL to values of structure 2 members, like IF STRUCTURE 1 = STRUCTURE 2 THEN....

    Thank you.
    Best regards,
    Zdenko.

    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.

    Thank you Scott,
    I already implemented this as you suggested. It works fine.

    In the memory library is a function "compare".
    This uses 2 pointers to memory blocks.
    If the result is 0, they are the same, otherwise the return value refers to the first byte where the difference is.
