CUresult-class: Class '"CUresult"'

In duncantl/RCUDA: R Bindings for the CUDA Library for GPU Computing

Description

Most of the CUDA routines return their information via pointers and explicitly return the status of the request as an enumerated constant. This is a CUresult. This is an integer value in R along with the symbolic name as the names vector (of length 1). This is a CUresult object in R.

Some CUDA routines just return the status when there is no information to return. These are typically set commands that don't query information. In these cases, the corresponding R functions return the status. However, if that value is not 0, the functions raise an error. The class of the error corresponds to the symbolic name of the status value. This allows us to handle the different errors with tryCatch. All possible values can be obtained with RCUDA:::CUresultValues.

For routines that return information via their arguments, the corresponding R function checks the return value to see if it is a CUresult (cudaResult_t) and raises an error if it is. This allows the R function to check the status but still return the values if there is no error.

Objects from the Class

Objects of class CUresult are typically generated in the C code and not within R code.
