formated Logger string problem solved

[KingFish <king.fish@myokay.net>]

Hi GameProgrammer user,

  it's me again...
  I solved the problem with the formatted strings by myself.

  For all who interrest in such code, here is the working one:

  #include <stdarg.h>

  void CLogger::Log(char *LogString ...) {

        va_list ArgList;
        
        va_start(ArgList, LogString);
        vfprintf(m_LogFileStream, LogString, ArgList);
        va_end(ArgList);

  }

  while ArgList is a pointer to the argument list, m_LogFileStream is
  a member variable which holds the FILE handle.

  This works perfect, tested with none or many arguments.

  So...

  One problem solved, but i have another one:

  I'm working on a class to write and read from/to a config file. I
  implemented also a method to write comments (c compliant, so with an
  following //) to the file. Here is the code that won't function in
  any fact:

  void CConfigurationFile::SaveComment(char *Value) {

        char *CommentString = "";

        strcpy(CommentString, "// ");
        strcat(CommentString, Value);
        strcat(CommentString, "\n");

        fputs(CommentString, m_ConfigFileStream);

  }

  while, m_ConfigFileStream is the FILE handle.

  The misterious about that is, that it will compile without an error
  but if the program is started and i want to write a comment into the
  already open file it crashes and nothing happened.
  If i debug this the debugger means, that there was access violation
  in strcat.asm.

  I'm not the perfect c coder, so i had now idea how to fix that,
  above all there is no logical error (that's my and the compiler's
  opinion ^_^) btw, like i said, i'm using VC++6.

  'Till the next mail...
