Hi
HB_FUNC... used when embedding C-code into .prg file
In the Harbour there is a possibility to insert fragments of C code in the prg file. This may be conveniently, if you don't want to create a .c file for a pair of C functions and then putting it in the project. This can be done with the help of directives #pragma BEGINDUMP ... #pragma ENDDUMP.

HB_FUNC...
{
// C/C++ code
}
#pragma ENDDUMP

Code: Select all

#pragma BEGINDUMP
   #include < extend.h >
   #include < math.h >
   HB_FUNC( SIN )
   {
      double x = hb_parnd(1);
      hb_retnd( sin( x ) );
   }
#pragma ENDDUMP
