You can store things for later!
drizzle> select libtcc("#include <string.h>\n#include <stdlib.h>\nint foo(char* s) { char *a= malloc(1000); return snprintf(s, 100, \"%p\", a); }") as RESULT;+-----------+ | RESULT | +-----------+ | 0x199c610 | +-----------+ 1 row in set (0 sec)
drizzle> select libtcc("#include <string.h>\n#include <stdlib.h>\nint foo(char* s) { char *a= 0x199c610; strcpy(a, \"Hello World!\"); strcpy(s,\"done\"); return strlen(s); }") as result;+--------+ | result | +--------+ | done | +--------+ 1 row in set (0.01 sec)
drizzle> select libtcc("#include <string.h>\n#include <stdlib.h>\nint foo(char* s) { char *a= 0x199c610; strcpy(s, a); return strlen(s); }") as result;+--------------+ | result | +--------------+ | Hello World! | +--------------+ 1 row in set (0.01 sec)
And then… i can disconnect, reconnect, or whatever (as for any of the above really) before cleaning up my memory:
drizzle> select libtcc("#include <string.h>\n#include <stdlib.h>\nint foo(char* s) { char *a= 0x19a9bc0; free(a); strcpy(s,\"done\"); return strlen(s); }") as result;+--------+ | result | +--------+ | done | +--------+ 1 row in set (0 sec)
