AST Parser failure

Dear Sir/Madam,

I have the following code inside a class.

//visit AST
static CXChildVisitResult TranslationUnitVisitor(CXCursor, CXCursor, CXClientData data)
{
return CXChildVisit_Recurse; // visit complete AST recursivly
}

void VisitTranslationUnitWithPCH()
{
//create function pointer
CXChildVisitResult (*pTranslationUnitVisitor)(CXCursor, CXCursor, CXClientData) = TranslationUnitVisitor;

//excludeDeclsFromPCH = 1, displayDiagnostics=1
CXIndex cx_idx = clang_createIndex(0, 1);

//IndexTest.pch was produced with the following command:
//“clang -x c test.h -emit-ast -o test.pch”
//system(“/home/socrates/llvm/Debug+Asserts/bin/clang -x c test.h -emit-ast -o test.pch”);
CXTranslationUnit TU = clang_createTranslationUnit(cx_idx, “test.pch”);

// This will load all the symbols from ‘test.pch’
clang_visitChildren(clang_getTranslationUnitCursor(TU), pTranslationUnitVisitor, 0);
clang_disposeTranslationUnit(TU);

// This will load all the symbols from ‘test.c’, excluding symbols
// from ‘test.pch’.
char *args = { “-Xclang”, “test.pch” };
TU = clang_createTranslationUnitFromSourceFile(cx_idx, “test.c”, 2, args, 0, 0);

clang_visitChildren(clang_getTranslationUnitCursor(TU), pTranslationUnitVisitor,0);
clang_disposeTranslationUnit(TU);
}

When I run it I get the following errors:

clang: ASTUnit.cpp:1064: bool clang::ASTUnit::Parse(llvm::MemoryBuffer*): Assertion `Clang->getFrontendOpts().Inputs.size() == 1 && “Invocation must have exactly one source file!”’ failed.

Err, did you mean { "-include", "test.pch" }? -Xclang doesn't make
any sense here.
