Writing S-Functions

ssPrintf

Print a variable-content message.

Syntax

• ssPrintf(msg, ...)
  

Arguments

• msg
  

Message. Must be a string with optional variable replacement parameters.

...
   Optional replacement arguments.

Description

Prints variable-content msg. This macro expands to mexPrintf when the S-function is compiled via mex for use with Simulink. When the S-function is compiled for use with the Real-Time Workshop, this macro expands to printf if the target has stdio facilities; otherwise, it becomes a call to an empty function (rtPrintfNoOp). In the case of Real-Time Workshop, you can avoid a call altogether, using the SS_STDIO_AVAILABLE macro. For example:

• #if defined(SS_STDIO_AVAILABLE)
      ssPrintf("my message ...");
  #endif
