[LLVMdev] What's the meaning of [0 x sbyte*]?

[夏一民]

Hi

When I compiled sendmail v8.11.6 with LLVM 1.2, I found some variables with 
strange type, such as: 
%sys_errlist = external constant [0 x sbyte*]           ; <[0 x sbyte*]*> [#uses=3]

%tmp.24 = getelementptr [0 x sbyte*]* %sys_errlist, long 0, long %tmp.23                ; <sbyte**> [#uses=1]

The process of getting these is:
1. entry sendmail-8.11.6 directory
2. make CC="/cfrontend/x86/llvm-gcc/bin/gcc"
3. entry obj.Linux.2.4.20-8.i686/sendmail
4. llvm-dis sendmail.bc &> sendmail.ins
5. grep "\[0 x sbyte*\]" sendmail.ins

What is the meaning of [0 x sbyte*]?
A pointer with the type of [0 x sbyte*]* is a void pointer?
