Return word length of storage container of registered data type
extern int ssGetDataTypeFxpContainWordLen (SimStruct *S,
DTypeId dataTypeId)
SSimStruct representing an S-function block.
dataTypeIdData type ID of the registered data type for which you want to know the container word length.
This function returns the word length, in bits, of the storage container of
the fixed-point data type designated by dataTypeId. This
function does not return the size of the storage container or the word length of
the data type. To get the storage container size, use ssGetDataTypeStorageContainerSize. To get the data type word
length, use ssGetDataTypeFxpWordLength.
To use this function, you must include fixedpoint.h and
fixedpoint.c. For more information, see Structure of the S-Function.
C
An sfix24_En10 data type has a word length of 24, but is
actually stored in 32 bits during simulation. For this signal,
ssGetDataTypeFxpContainWordLen returns
32, which is the storage container word length in
bits.
ssGetDataTypeFxpWordLength returns
24, which is the data type word length in
bits.
ssGetDataTypeStorageContainerSize or
sizeof( ) returns 4, which is
the storage container size in bytes.
