strstream::strstream

strstream();

strstream( char* pch, int nLength, int nMode );

Parameters

pch

A character array that is large enough to accommodate future output stream activity.

nLength

The size (in characters) of pch. If 0, pch is assumed to point to a null-terminated array; if less than 0, the array is assumed to have infinite length.

nMode

The stream creation mode, which must be one of the following enumerators as defined in class ios:

• ios::in   Retrieval begins at the beginning of the array.
  
  
• ios::out   By default, storing begins at pch.
  
  
• ios::ate   The pch parameter is assumed to be a null-terminated array; storing begins at the NULL character.
  
  
• ios::app   Same as ios::ate.

  The use of the ios::in and ios::out flags is optional for this class; both input and output are implied.

Remarks

The first constructor makes an strstream object that uses an internal, dynamic buffer that is initially empty.

The second constructor makes an strstream object out of the first nLength characters of the psc buffer. The stream will not accept characters once the length reaches nLength.
