Since R2020b

Syntax

extern int ssGetDataTypeIsInteger(SimStruct *S,
                                         DTypeId dataTypeId,
                                         int isSigned,
                                         int wordLength)

Arguments

S

SimStruct representing an S-function block.

dataTypeId

Data type ID of the registered data type to analyze, specified as a DTypeId. To retrieve the DTypeId of a registered data type, use ssGetDataTypeId.

isSigned

Whether the specified integer is signed. Specify TRUE if the integer data type is signed or FALSE if the integer data type is unsigned.

wordLength

Total number of bits in the specified integer, including any sign bit, specified as a whole number between 1 and 65535.

Returns

This function returns 1 if the registered data type is the specified integer, and 0 otherwise.

Description

This function determines whether a registered data type is the integer data type with the word length and signedness that are specified in the function arguments.

Requirement

To use this function, you must include fixedpoint.h and fixedpoint.c.
