StrRef::StrRef( const char * , int ) (constructor)

Construct a StrRef, referencing an existing string.

Virtual?	No
Class	StrRef
Arguments	char *buf	a null-terminated string to reference
	int len	the string length
Returns	StrRef

Notes

If arguments are provided, the constructor calls Set() with them.

StrRef::Set() does not copy the target string; it simply creates a pointer to it. Be sure that the StrRef pointing to the target string does not outlive the target string.

Example

#include <iostream>

#include <stdhdrs.h>
#include <strbuf.h>

int main( int argc, char **argv )
{
    char chars[] = "xyzzy";
    StrRef sr = StrRef( chars, 3 );
    StrBuf sb;
    sb.Set( sr );

    printf( "chars[] = \"%s\"\n", chars );
    printf( "sr.Text() returns \"%s\"\n", sr.Text() );
    printf( "sb.Text() returns \"%s\"\n", sb.Text() );

    return 0;
}

Executing the preceding code produces the following output:

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