9 | * any single quote is replaced with '\'', any exclamation point |
10 | * is replaced with '\!', and the whole thing is enclosed in a | |
11 | * single quote pair. | |
6fb737be JH |
12 | * |
13 | * For example, if you are passing the result to system() as an | |
14 | * argument: | |
15 | * | |
16 | * sprintf(cmd, "foobar %s %s", sq_quote(arg0), sq_quote(arg1)) | |
17 | * | |
18 | * would be appropriate. If the system() is going to call ssh to | |
19 | * run the command on the other side: | |
20 | * | |
21 | * sprintf(cmd, "git-diff-tree %s %s", sq_quote(arg0), sq_quote(arg1)); | |
22 | * sprintf(rcmd, "ssh %s %s", sq_quote(host), sq_quote(cmd)); | |
23 | * | |
24 | * Note that the above examples leak memory! Remember to free result from | |
25 | * sq_quote() in a real application. | |

26 | * |
27 | * sq_quote_buf() writes to an existing buffer of specified size; it | |
28 | * will return the number of characters that would have been written | |
29 | * excluding the final null regardless of the buffer size. | |

31 | * sq_quotef() quotes the entire formatted string as a single result. | |
