Pointer problems

[Brenton S.]

Hi all,

I created a function that skips past white spaces in a string:

 
VOID SkipSpaces(LPSTR lpszString)
{
 while(isspace(*lpszString))
 {
  lpszString ++;
 }
}

I know it works, but when I call it nothing happens:

 
LPSTR lpszBuffer = "	 Hello World";
  
SkipSpaces(lpszBuffer);
 
printf(lpszBuffer); // lpszBuffer still equals "	Hello World"
						// it should equal "Hello World"

I think it might be a problem with pointers:

lpszString ++;

Does anybody know what the problem may be?

You need a pointer to a pointer:

VOID SkipSpaces(LPSTR* lpszString)
{
  while(isspace((*lpszString)[0]))
  {
    ++(*lpszString);
  }
}
