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; }
