B4J Question How does B4X call C language function code?

[daiweisc]

How does B4X call C language function code?
C language Structure is created by unpacking the ANSI C release tar / zip files.
For example the codes in ANSI C:

#include "sofa.h"
#include "sofam.h"
int iauApco13(double utc1, double utc2, double dut1, double elong, double phi, double hm, double xp, double yp, double phpa, double tc, double rh, double wl, iauASTROM *astrom, double *eo)

Don't think it is possible. B4X can call C compiled dll via JNI though.

Can I use inline java method？If Yes, How to modify the C language Structure.

 

[Erel]

You cannot directly call C code from B4J or Java.

 

[Quandalle]

The easiest way is to compile the C code in the form of an external executable program (Linux or Windows) with a standard C compiler.
B4X can then be used to launch this external program and wait for it to finish executing (cf jShell ).
Parameters can be passed by file or command line.
Results can be passed by file or on the console stream.
