Syntax

int_T ssSetDataTypeSize(SimStruct *S, DTypeId id, int_T size)

Arguments

S
SimStruct representing an S-Function block.

id
ID of data type.

size
Size of the custom data type in bytes.

Sets the size of the data type specified by id to size. If the call is successful, the macro returns 1 (true), otherwise, it returns 0 (false). Use this macro in mdlInitializeSizes to set the size of a data type you have registered.

Example

The following example registers and sets the size of the custom data type named Color to 4 bytes.

int_T   status;
DTypeId id;

id = ssRegisterDataType(SimStruct *S, "Color");
if(id == INVALID_DTYPE_ID) return;

status = ssSetDataTypeSize(S, id, 4);
if(status == 0) return;
