Writing S-Functions

ssSetDWorkRTWStorageClass

Specify the storage class of a DWork vector in code generated from the associated S-function.

Syntax

• void ssSetDWorkRTWStorageClass(SimStruct* S, int idx, 
  

ssRTWStorageType sc)

Arguments

S
   SimStruct representing an S-Function block.

idx
   Index of the work vector, where the index is one of 0, 1, 2, ... ssGetNumDWork(S).

sc
   Storage class of the work vector. Must be one of the values enumerated by ssRTWStorageType in simstruc.h:

• typedef enum { 
      SS_RTW_STORAGE_AUTO = 0, 
      SS_RTW_STORAGE_EXPORTED_GLOBAL, 
      SS_RTW_STORAGE_IMPORTED_EXTERN, 
      SS_RTW_STORAGE_IMPORTED_EXTERN_POINTER 
  } ssRTWStorageType
  

Description

Sets sc as the storage class of the the DWork vector specified by idx. The storage class is a code-generation attribute that determines how the code generated by the Real-Time Workshop for this S-function allocates memory for this work vector (see Signal Storage Concepts in the online documentation for the Real-Time Workshop).

Languages

C, C++
