StrBuf::operator <<( const char * )
Append a null-terminated string to a StrBuf
. The string is
logically appended to the string pointed to by the StrBuf
's
buffer
.

|
(implied) pointer to the first byte of the null-terminated string |

reference of the |
Notes
The StrBuf
's length
is incremented by the
number of bytes prior to the first null byte in the string.
If the memory for the StrBuf
's buffer
is not
large enough, new contiguous memory is allocated to contain the results
of appending the null-terminated string. If new memory is allocated, the
old memory is freed. Any memory allocated is separate from the memory for
the string.
Example
#include <iostream> #include <stdhdrs.h> #include <strbuf.h> int main( int argc, char **argv ) { char chars[] = "zy"; StrBuf sb; sb.Set( "xyz" ); cout << "sb.Text() prior to sb << chars returns "; cout << "\"" << sb.Text() << "\"\n"; cout << "sb.Length() prior to sb << chars returns "; cout << sb.Length() << "\n\n"; sb << chars; // append char * to StrBuf cout << "sb.Text() after sb << chars returns "; cout << "\"" << sb.Text() << "\"\n"; cout << "sb.Length() after sb << chars returns "; cout << sb.Length() << "\n"; }
Executing the preceding code produces the following output:
sb.Text() prior to sb << chars returns "xyz" sb.Length() prior to sb << chars returns 3 sb.Text() after sb << chars returns "xyzzy" sb.Length() after sb << chars returns 5
