Mod template error in Utlbuffer.cpp

[city14]

I'm getting an assert error in UtlBuffer.cpp

assertion failed nSize!=0

Here's the code block I'm assuming the error stems from...

Code: Select all

//-----------------------------------------------------------------------------
// constructors
//-----------------------------------------------------------------------------
CUtlBuffer::CUtlBuffer( int growSize, int initSize, int nFlags ) :
   m_Memory( growSize, initSize ), m_Error(0)
{
   m_Get = 0;
   m_Put = 0;
   m_nTab = 0;
   m_nOffset = 0;
   m_Flags = nFlags;
   if ( (initSize != 0) && !IsReadOnly() )
   {
      m_nMaxPut = -1;
      AddNullTermination();
   }
   else
   {
      m_nMaxPut = 0;
   }
   SetOverflowFuncs( &CUtlBuffer::GetOverflow, &CUtlBuffer::PutOverflow );
}

CUtlBuffer::CUtlBuffer( const void *pBuffer, int nSize, int nFlags ) :
   m_Memory( (unsigned char*)pBuffer, nSize ), m_Error(0)
{
   Assert( nSize != 0 );  < - Right here is where it said it broke line 220

   m_Get = 0;
   m_Put = 0;
   m_nTab = 0;
   m_nOffset = 0;
   m_Flags = nFlags;
   if ( IsReadOnly() )
   {
      m_nMaxPut = nSize;
   }
   else
   {
      m_nMaxPut = -1;
      AddNullTermination();
   }
   SetOverflowFuncs( &CUtlBuffer::GetOverflow, &CUtlBuffer::PutOverflow );
}

Anyone know how to fix this?

simple. Dont create CUtlBuffer with a zero size. Quite pointless to create one with 0 length, hence the Assertion was placed.

The cause is not in this code. Somewhere you are saying CUtlBuffer b = new CUtlBuffer( buff, 0, flags); which is wrong.

K, thanks! Didn't realize how noobish that was...

This is a old thread but

Turns out, these ARE the drones you are looking for.
