We want to eventually drop the use of the "argv_array" name in favor of "strvec." Unlike most other uses of the name, this one is embedded in a function name, so the definition and all of the callers need to be updated at the same time. We don't technically need to update the parameter types here (our preprocessor compat macros make the two names interchangeable), but let's do so to keep the site consistent for now.

|
|
* 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

|
|
*
|
|
* 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.
|
|

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