    To free an SV that you've created, call "SvREFCNT_dec(SV*)". Norma
+lly
    this call is not necessary (see "Reference Counts and Mortality").

You do not free SV, you decrement its usage, and, when refcount goes to zero, it will be destroyed, and may be some destruction-time action will be activated

addition to free memory out from external library, consult that library's logic. Perl do not uses external char*, it will copy its data into newly created SV

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
