strcat() function

Rabbit
1

Hi, I’m new to using Dynamic C and Rabbit technology, but as a kind of ‘hello world’ type of application I’ve been trying to make a function to translate a char* plain-text alphanumerical message into a string of morse code (using dots, dashes, slashes, and spaces). I’ve already implemented the functions which translate a single character into morse code, and which interpret a morse-code string and make one of the module’s LEDs flash the morse code.

However, attempting to iterate through each character in the char* to translate into morse code and then concatenate it to a longer string, I’ve come across a problem with Dynamic C’s strcat() function.

Important bit :wink:
strcat() doesn’t remove the \0 from the end of the first string before appending the second, so the null-terminated string essentially remains the same. What’s the easiest way to correct this problem?

Thanks in advance for any suggestions.

:confused:

Works OK for me. Are you sure you’ve got the arguments in the right order?

I just tried this with DC10.50:

   strcpy(buf, "Hello ");
   strcat(buf, "world");
   printf("buf = %s
", buf);

I get:
buf = Hello world

Perhaps it has been updated? When I try the same thing, the string is simply "Hello ". Perhaps I’ll try updating my version of Dynamic C.
