This callback function is provided by the Web Server. ISAPI filters call this function to allocate memory from the process heap to a buffer. The AllocMem name for this function is a placeholder for the function name defined by the header. Any memory allocated with this function will automatically be freed by the Web Server when the session ends.

Syntax

VOID* WINAPI* AllocMem(
  PHTTP_FILTER_CONTEXT pfc,
  DWORD cbSize,
  DWORD dwReserved 
);

Parameters

  • pfc
    [in] Pointer to an HTTP_FILTER_CONTEXT structure that is associated with the current, active HTTP transaction.
  • cbSize
