Checks the device memory type.

aclError aclrtCheckMemType(void** addrList, uint32_t size, uint32_t memType, uint32_t *checkResult, uint32_t reserve)

Parameter	Input/Output	Description
addrList	Input	Device memory address array.
size	Input	Size of the addrList array.
memType	Input	Device memory type. The following macros are supported: ACL_RT_MEM_TYPE_DEV Device memory allocated by calling the aclrtMalloc or aclrtMallocWithCfg API. #define ACL_RT_MEM_TYPE_DEV (0X2U) ACL_RT_MEM_TYPE_DVPP Dedicated device memory for DVPP. The memory can be allocated by calling a memory allocation API (for example, hi_mpi_dvpp_malloc). ACL_RT_MEM_TYPE_RSVD Virtual memory reserved by calling aclrtReserveMemAddress. #define ACL_RT_MEM_TYPE_RSVD (0X10U) If the addrList array contains different types of memory addresses, the value of memType must be set to bitwise OR of the memory types. For example, RT_MEM_MASK_DEV_TYPE \| RT_MEM_MASK_DVPP_TYPE.
checkResult	Output	Whether the memory address type in the addrList array matches the value of memType. 1: match 0: not match
reserve	Input	Reserved. The value is fixed at 0.

0 on success; else, failure. For details, see aclError.
