| | 9 | * For example, if you are passing the result to system() as an |
| | 10 | * argument: |
| | 11 | * |
| | 12 | * sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1)) |
| | 13 | * |
| | 14 | * would be appropriate. If the system() is going to call ssh to |
| | 15 | * run the command on the other side: |
| | 16 | * |
| | 17 | * sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1)); |
| | 18 | * sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd)); |
| | 19 | * |
| | 20 | * Note that the above examples leak memory! Remember to free result from |
| | 21 | * sq_quote() in a real application. |
