======**sqInt getAttributeIntoLength(sqInt indexNumber, sqInt byteArrayIndex, sqInt length)**======

**Parms**:
indexNumber, a negative or positive number, or zero
byteArrayIndex a pointer to squeak memory, use pointerForOop(byteArrayIndex) to convert
length an agreed upon length for the storage area.

**return**: char*, or sucess(0) to fail primitive.
**From**: Interpreter
**Why**:
Returns char* to an empty string or magic value strings. which might be arguments to the VM at startup.
Works in conjunction with attributeSize which calls it to get data and use that for sizing.
Do NOT return NULL
ON unix systems for numbers < 0 it returns the arguments passed to the program via the cmd line
On unix systems for numbers > 2 it returns the
number == 0 return vmName
number == 1 return imageName
number == 1001 /* OS type: "unix", "win32", "mac", ... */
number == 1002 /* OS name: "solaris2.5" on unix, "win95" on win32, ... */
number == 1003 /* processor architecture: "68k", "x86", "PowerPC", ... */
number == 1004 /* Interpreter version string */
number == 1006 /* build string, say "Unix built on "__DATE__ " "__TIME__" Compiler: "__VERSION__ */

//Cocoa://
if indexNumber < 0 and negated is between 1 and the number of arguments then return the start up argument as a char*
if indexNumber is > 0 and if you subtract 2 from it and it is between 1 and the number of arguments then return the startup argument as char*

**iPhone**
if indexNumber < 0 and negated is between 1 and the number of arguments then return the start up argument as a char*
{However on the iPhone it's hard to say how you would pass in an argument since there is no cmd-line interface}
if indexNumber is > 0 and if you subtract 2 from it and it is between 1 and the number of arguments then return the startup argument as char*

**BUGS**
If attributeSize(1) followed by getAttribute(1) does not return the same sized element the results will be bogus.
Possible memory corruption can occur.
