Hi,

This I have read from some website:

X int * Y p ;
means that the pointer p is stored in the Y memory. This pointer points to integer data that is located in the X memory. If no memory qualifiers are used, the data is stored into unqualified memory.

For proper integration with the C language, a memory structure is specified, where the unqualified memory encompasses all other memories. All unqualified pointers are pointers into this unqualified memory.

Huh? As far as I know qualified types are types with 'volatile' or 'const' added to
the type:

Expand|Select|Wrap|Line Numbers

 
volatile int x; // qualified

volatile int* px; // qualified

int y; // unqualified

int *py; // unqualified

// etc.

kind regards,

Jos

Even I didn't know. Just a new question and I search the web and found this.

Thanks for clear explanation :)
