| hello_sip - learn to add your own C routine to SIP |

| a |
| double-precision scalar |
| b |
| double-precision scalar |
| c |
| double-precision scalar |
| "hello_sip" is a very simple example routine. The aim is that new developers know quickly how to add a new C-language implemented function to SIP. |
| hello_sip(a,b) simply returns a + b through a C routine. |
| The following files in the SIP sourcecode tree are related to the implementation of hello_sip: |
| src/hello_int.c -- |
| interfaces C to Scilab |
| src/builder.sce -- |
| specifies the interface files and scilab name; this script is ran by Scilab to compile the interface C routines into a shared library. |
| From AnImaL (aminal.sourceforge.net), |
| animal/hello.c -- routine that returns a+b |
| From AnImaL (aminal.sourceforge.net), |
| animal/hello.h -- header with the prototype of hello |
| From AnImaL (aminal.sourceforge.net), |
| animal/animal.h general header for the internal C library |

| In the SIP source tree, start with the "hello.c" file inside the directory "src". |
| Obsoleted: Figure 1 of the first SIP monograph (written in portuguese), which may be found in the SIP home page. SIP now uses an independent computer vision library, AnImaL, for its internal processing. See: http://animal.sourceforge.net |
| Moreover, in the scilab source tree, the directories "examples/interface-tour.so" and "examples/interface-tutorial.so" provide detailed information on interfacing C and Scilab. |
