Operator: __VCSTORE

The operator saves/copies the contents of the vector to the specified memory address. The number and the types of elements are automatically applied from the vector variables.

NOTICE

‎__VCSTORE(<n>,<ptr>)‎ writes ‎<n>‎ successive values at the ‎<ptr>‎ address. If there are less than ‎<n>‎ values at this address, then this can cause the controller to crash or write unwanted memory.

Syntax

__VCSTORE( <pointer to data>, <vector variable> );
