ilib_gen_gateway — utility for ilib_build, generates a gateway file.
ilib_gen_gateway(name,table)
a character string, the generic name of the library without path and extension.
2 column string matrix giving the table of pairs 'scilab-name' 'interface name'
Utility function used by ilib_build This function
generates a gateway file used by addinter.
if WITHOUT_AUTO_PUTLHSVAR variable is defined and equals to %t, PutLhsVar(); will need to manage PutLhsVar in each interface as internal scilab functions.
In another case (default, for compatibility with previous version) , PutLhsVar(); is added in each interface.
You can also see SCI/contrib/toolbox_skeleton/sci_gateway/c/builder_gateway_c.sce (as example about WITHOUT_AUTO_PUTLHSVAR)
cd TMPDIR WITHOUT_AUTO_PUTLHSVAR = %t; name = 'gw_example1'; table = ['sci_func1', 'func1'] ilib_gen_gateway(name,table) // generated gateway mgetl(TMPDIR+'/gw_example1.c')
int sci_func1(char *fname)
{
// ... your C code
// you need to add a explicit PutLhsVar();
// as internal all gateways of scilab
PutLhsVar();
return 0;
}cd TMPDIR WITHOUT_AUTO_PUTLHSVAR = %f; name = 'gw_example2'; table = ['sci_func2', 'func2'] ilib_gen_gateway(name,table) // generated gateway mgetl(TMPDIR+'/gw_example2.c')
int sci_func2(char *fname)
{
// ... your code
// you do NOT need to add a explicit PutLhsVar();
// added by scilab after call to sci_func2
// default mode in scilab 4
return 0;
