This is an old C function but it's used in a 3rd party lib so I can't
use HB's standard one.
When I build it with 2.0.0beta3 gcc warnings. How can I fix it?
#include <extend.h>
#ifdef __HARBOUR__
HB_FUNC( BIT )
#else
CLIPPER bit( void )
#endif
{
char *ptr;
unsigned char mask;
unsigned int loc,
offset = _parni( 2 ) - 1,
res = 0;
loc = offset / 8;
if ( loc < _parclen( 1 ) )
{
ptr = _parc( 1 ) + loc; <---- warning here
loc = offset % 8;
res = *ptr << loc & 0x80;
if ( PCOUNT > 2 )
{
mask = (unsigned char ) 0x80 >> loc;
if ( _parl( 3 ) )
*ptr = *ptr | mask;
else
*ptr = *ptr & ~mask;
}
}
_retl( res );
}
best regards,
Lorenzo
