[scilab-Users] API_Scilab example

Tue Apr 10 21:01:24 CEST 2012

Dear Sylvestre,

Thank you again for your reply. In the 5.4 alpha, the documentation for 
CheckInputArgument/CheckOutputArgument is not (yet) there. As intersci 
still works quite ok in 5.4 alpha (and actually works ok for x64 for 
this version, did not manage to resolve linking issues in previous 
versions) I will stick with intersci until API Scilab and perhaps an 
alternative to intersci in combination with dynamic linking crystallizes 
out. Would much like to hear about SWIG once available (if developments 
indeed will head in that direction). I may switch to call_scilab in the 
mean time for getting scilab to start, as that appears to go a lot 
faster than starting it in a separate process, which is what I do now.

Best wishes,

Jasper.
