Writing S-Functions

ssRegisterDataType

Register a custom data type.

Syntax

• DTypeId ssRegisterDataType(SimStruct *S, char *name)
  

Arguments

S
   SimStruct representing an S-Function block.

name
   Name of custom data type.

Description

Register a custom data type. Each data type must be a valid MATLAB identifier. That is, the first char is an alpha and all subsequent characters are alphanumeric or "_". The name length must be less than 32. Data types must be registered in mdlInitializeSizes.

If the registration is successful, the function returns the DataTypeId associated with the registered data type; otherwise, it reports an error and returns INVALID_DTYPE_ID.

After registering the data type, you must specify its size, using ssSetDataTypeSize.

Note    You can call this function to get the data type ID associated with a registered data type.

Example

The following example registers a custom data type named Color.

• DTypeId id = ssRegisterDataType(S, "Color");
  if(id == INVALID_DTYPE_ID) return;
