compare two string of messages

I am new in the use of dinamic C, somebody can tell me how I can compare two string of messages, have a manual of old dimanic C and here there is an instruction �strcmp� to compare string but it does not tell me me like doing, Somedody can help me.

Hi. the strcmp function compare 2 character arrays ( Null or 0 character terminate). and return 0 if they are equals. if you have any character different or the length array are different (see the 0 character position), for this function are diferents.
see more documentation in help->Function lookup in the menu. or Ctrl+H over
strcmp function in your editor
