strstream::strstream

Constructs an object of type strstream.

strstream( ); 
strstream( 
   char *_Ptr,  
   streamsize _Count, 
   ios_base::openmode _Mode = ios_base::in | ios_base::out 
);

Parameters

  • _Count
    The size of the buffer.

  • _Mode
    The input and output mode of the buffer. See ios_base::openmode for more information.

  • _Ptr
    The buffer.

Remarks

Both constructors initialize the base class by calling streambuf(sb), where sb is the stored object of class strstreambuf. The first constructor also initializes sb by calling strstreambuf. The second constructor initializes the base class one of two ways:

  • If _Mode & ios_base::app== 0, then _Ptr must designate the first element of an array of _Count elements, and the constructor calls strstreambuf(_Ptr, _Count, _Ptr).

  • Otherwise, _Ptr must designate the first element of an array of count elements that contains a C string whose first element is designated by _Ptr, and the constructor calls strstreambuf( _Ptr, _Count, _Ptr + strlen(_Ptr) ).
