- * @return #hipSuccess, #hipErrorInvalidValue
+ * @param[in] symbol  The Symbol name of the driver function to request.
+ * @param[out] pfn  Output pointer to the requested driver function.
+ * @param[in] hipVersion  The HIP version for the requested driver function symbol.
+ * HIP version is defined as 100*version_major + version_minor. For example, in HIP 6.1, the
+ * hipversion is 601, for the symbol function "hipGetDeviceProperties", the specified hipVersion 601
+ * is greater or equal to the version 600, the symbol function will be handle properly as backend
+ * compatible function.
+ *
+ * @param[in] flags  Currently only default flag is suppported.
+ * @param[out] symbolStatus  Optional enumeration for returned status of searching for symbol driver
+ * function based on the input hipVersion.
+ *
+ * Returns hipSuccess if the returned pfn is addressed to the pointer of found driver function.
+ *
+ * @return #hipSuccess, #hipErrorInvalidValue.
