StrBuf::Set( const char *, int )

Set a StrBuf from a string of a specified length.

Virtual?	No
Class	`StrBuf`
Arguments	`const char *buf`	pointer to the first byte of the string
	`int len`	length of the string
Returns	`void`

Notes

Initialize the StrBuf before calling Set().

Exactly len bytes are copied from the string to the StrBuf. The length of the StrBuf is set to the len argument.

Any memory allocated for the StrBuf's buffer is separate from the memory for the string.

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";
    StrBuf sb;

    sb.Set( chars, 3 );   // set StrBuf from len bytes of char *

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

Executing the preceding code produces the following output:

chars[] = "xyzzy"
sb.Text() returns "xyz"
