Number of bits: ptrdiff_t

Description

Describe the bit-length of ptrdiff_t data for the hardware that you use to test code.

If ProdEqTarget is off, an Embedded Coder^® processor-in-the-loop (PIL) simulation checks this setting with reference to the target hardware. If ProdEqTarget is on, the PIL simulation checks the ProdBitPerPtrDiffT setting.

Category: Hardware Implementation

Settings

Default: 64

Value must be 8, 16, 24, 32, 40, 64, or 128 and greater or equal to the value of int.

Dependencies

• Selecting a device by using the Device vendor and Device type parameters sets a device-specific value for this parameter.

• This parameter is enabled only if you can modify it for the selected hardware.

Command-Line Information

Parameter: TargetBitPerPtrDiffT

Type: integer

Value: any valid value

Default: 64

Recommended Settings

Application	Setting
Debugging	No impact
Traceability	No impact
Efficiency	No impact
Safety precaution	No impact when Test hardware is the same as production hardware is selected. If it is not selected, no recommendation.
