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