Lee Doron commented on XERCESC-1986:
------------------------------------
Agreed. Consider the following test code -- when you run it (try
http://codepad.org/ZsmOvOAZ for convenience), you get "4, 256, 256". The value
returned into "len" is 4 because the array type decayed into a pointer when
used as a parameter (see http://stackoverflow.com/a/1570616/768820 for details):
#include <stdio.h>
typedef unsigned char s255[256];
int siz(s255 pas)
{
return sizeof(pas);
}
int main()
{
s255 pas2;
int len = siz(pas2);
printf("%d, %d, %d\n", len, sizeof(pas2), sizeof(s255));
}

> sizeof(pas) must be replace by sizeof(Str255), because sizeof(pas) returns
> sizeof(unsigned char *) and not sizeof(unsigned char[256]) as desired.
