Data-Type Misalignment

A data-type misalignment exception is generated when an attempt is made to load or store data in an address that is not naturally aligned on a hardware architecture that does not provide alignment hardware. For example, 16-bit entities must be aligned on two-byte boundaries, and 32-bit entities must be aligned on four-byte boundaries. This exception does not occur on the Intel 80386 processor. This exception is continuable.

Exception Code:

XCPT_DATATYPE_MISALIGNMENT (0xC000009E)
Default Action:
The process is ended.
Additional Parameters (3):

Exception Info[ 0 ]

Read/Write Flag XCPT_READ_ACCESS, or
XCPT_WRITE_ACCESS.

Exception Info[ 1 ]
Data-type Mask

A data-type mask that specifies how many low-address bits must be zero. For example, the data-type mask for a 16-bit entity is one, a 32-bit entity three, and so on.

Exception Info[ 2 ]
Virtual Address

The virtual address of the misaligned data.
