StrRef::operator +=( int )

Increase a StrRef’s pointer and decrease its length.

Virtual?	No
Class	`StrRef`
Arguments	`int len`	the amount by which to move the pointer
Returns	`void`

Notes

This method has the effect of removing len characters from the beginning of the StrRef. It does not, however, free the memory allocated to those characters.

Example

Copy

#include &lt;iostream&gt;

#include &lt;stdhdrs.h&gt;
#include &lt;strbuf.h&gt;

int main( int argc, char **argv )
{
    char chars[] = "xyzzy";
    StrRef sr = StrRef( chars );

    sr += 3;

    cout &lt;&lt; "chars[] = \"" &lt;&lt; chars &lt;&lt; "\"\n";
    cout &lt;&lt; "sr.Text() returns \"" &lt;&lt; sr.Text() &lt;&lt; "\"\n";
}

Executing the preceding code produces the following output:

chars[] = "xyzzy"
sr.Text() returns "zy"
