syntax - Is it possible to define a CAPL function returning a text string? -

i develop capl scripts in vector canoe, , need define several functions returning text strings. in c, write this:

char * errorcodetomsg(int code)

char [] errorcodetomsg(int code)

in capl, both definitions fail parse error. working solution came far is:

variables {   char retval[256]; }  void errorcodetomsg(int code) {   char [] msg = "hello word";   strncpy(retval, msg, 256); }

of course ugly, because each call errorcodetomsg requires 2 statements instead of one. there better way?

you have string-based functions :

 void errorcodetomsg(char buffer[], int code){  buffer = mylistofcodes[code];  }

the value stored in buffer using reference value. not possible return string in capl. why can't access string system variables using @ selector.
