*devPtr the address of symbol
symbol on the device.
symbol can either be a variable that resides in global or constant memory space, or it can be a character string, naming a variable that resides in global or constant memory space. If
symbol cannot be found, or if
symbol is not declared in the global or constant memory space,
*devPtr is unchanged and the error cudaErrorInvalidSymbol is returned. If there are multiple global or constant variables with the same string name (from separate files) and the lookup is done via character string, cudaErrorDuplicateVariableName is returned.
|devPtr ||- Return device pointer associated with symbol |
|symbol ||- Global variable or string symbol to search for|

- Note that this function may also return error codes from previous, asynchronous launches.
