Initializes and starts Scilab engine in Call Scilab

BOOL StartScilab(char *SCIpath, char *ScilabStartup, int


This fonction starts the Scilab engine. This is mandatory to use SendScilabJob functions and to manage Scilab's data.

BOOL is just a simple typedef on int (typedef int BOOL). TRUE is defined on 1 (#define TRUE 1) and FALSE is defined on 0 (#define FALSE 0).



a standard C char* containing the path to Scilab data

This argument is mandatory under Linux, Unix or Mac OS X.

Under Windows, if SCIpath is NULL, Scilab will find the path.


a standard C char* containing the path to Scilab startup script (scilab.start)

If ScilabStartup is NULL, Scilab will use the default path (detected from SCIpath).


a standard int* defining the size of the Scilab stack

If Stacksize is NULL, Scilab will use the default stacksize of Scilab.


1 (TRUE) if the operation is successfull.

0 (FALSE) if an error during initialization occured.


// A simple StartScilab example
if ( StartScilab(getenv("SCI"),NULL,NULL) == FALSE )
  fprintf(stderr,"Error while calling StartScilab\n");
  return -1;
