CHString::ReleaseBuffer method (chstring.h)

[The CHString class is part of the WMI Provider Framework which is now considered in final state, and no further development, enhancements, or updates will be available for non-security related issues affecting these libraries. The MI APIs should be used for all new development.]

The ReleaseBuffer method ends the use of a buffer allocated by GetBuffer.


void  throw(CHeap_Exception) ReleaseBuffer(
  int nNewLength



The new length of the string in characters, not counting a terminating null character.

If the string is NULL-terminated, the –1 default value sets the CHString string size to the current length of the string.

Return value

This method does not return a value.


If you know that the string in the buffer is NULL-terminated, you can omit the nNewLength parameter. If your string is not NULL-terminated, then use nNewLength to specify its length. The address returned by GetBuffer is not valid after the call to ReleaseBuffer or any other CHString operation.
