Detailed Description
This section describes the error handling functions of HIP runtime API.
Function Documentation
◆ hipGetErrorName()
| const char * hipGetErrorName | ( | hipError_t | hip_error | ) |
Return name of the specified error code in text form.
- Parameters
-
hip_error Error code to convert to name.
- Returns
- const char pointer to the NULL-terminated error name
- See also
- hipGetErrorString, hipGetLastError, hipPeakAtLastError, hipError_t
◆ hipGetErrorString()
| const char * hipGetErrorString | ( | hipError_t | hipError | ) |
Return handy text string message to explain the error which occurred.
- Parameters
-
hipError Error code to convert to string.
- Returns
- const char pointer to the NULL-terminated error string
- Warning
- : on HCC, this function returns the name of the error (same as hipGetErrorName)
- See also
- hipGetErrorName, hipGetLastError, hipPeakAtLastError, hipError_t
◆ hipGetLastError()
| hipError_t hipGetLastError | ( | void | ) |
Return last error returned by any HIP runtime API call and resets the stored error code to hipSuccess.
- Returns
- return code from last HIP called from the active host thread
Returns the last error that has been returned by any of the runtime calls in the same host thread, and then resets the saved error to hipSuccess.
- See also
- hipGetErrorString, hipGetLastError, hipPeakAtLastError, hipError_t
◆ hipPeekAtLastError()
| hipError_t hipPeekAtLastError | ( | void | ) |
Return last error returned by any HIP runtime API call.
- Returns
- hipSuccess
Returns the last error that has been returned by any of the runtime calls in the same host thread. Unlike hipGetLastError, this function does not reset the saved error code.

- hipGetErrorString, hipGetLastError, hipPeakAtLastError, hipError_t
