/* Help to copy the thing properly quoted for the shell safety. |
|
* any single quote is replaced with '\'', any exclamation point |
|
* is replaced with '\!', and the whole thing is enclosed in a |
|
* single quote pair. |
|
* |
|
* For example, if you are passing the result to system() as an |
|
* argument: |
|
* |
|
* sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1)) |
|
* |
|
* would be appropriate. If the system() is going to call ssh to |
|
* run the command on the other side: |
|
* |
|
* sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1)); |
|
* sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd)); |
|
* |
|
* Note that the above examples leak memory! Remember to free result from |
|
* sq_quote() in a real application. |
|
* |
|
* sq_quote_buf() writes to an existing buffer of specified size; it |
|
* will return the number of characters that would have been written |
|
* excluding the final null regardless of the buffer size. |
