char* gaadebug_answer_string (
     gaa_ptr gaa,
     char * out,
     int osize,
     gaa_answer * ans)
 

Express the answer in a string.

Parameters:
gaa input gaa pointer
out output string
osize input maximum size of out string
ans input answer
Return values:
<some_string> answer string returned on success
0 failure
Note:
In a multithreaded environment, the starting and ending times in the string may be incorrect (because this function relies on gmtime, which does not appear to be thread-safe).
