Sal_* types have been created to be helpers. They need to be strictly preserved when dealing with ABI and/or data-serialization. Some code mix Sal_* types with other types.
- Because they map to different integral types on different platforms, using them with printf style functions (such as OSL_TRACE) is cumbersome.
- Fortunately there is a SAL_DEBUG macro that uses stream overloads so you don't need to worry about the types when debugging:
SAL_DEBUG("GetLayoutOffset " << nLayout);
- Here are some examples of how to correctly use them with printf style functions if you really have to (but it's much easier to use SAL_DEBUG instead):
1) i is defined as sal_uInt32 so:
DBG(printf( "call ImplCreateSlide( %"SAL_PRIuUINT32" )\n", i));
DBG(printf( "call ImplCreateSlide( %d )\n", i));
2) nLayout is defined as sal_Int32 so :
DBG(printf("GetLayoutOffset %"SAL_PRIdINT32"\n", nLayout));
DBG(printf("GetLayoutOffset %d\n", nLayout));
3) intValue is defined as sal_Int32 and you want hex value :
printf ("%"SAL_PRIdINT32" (hex: %"SAL_PRIxUINT32")\n", intValue, intValue);
printf ("%d (hex: %x)\n", intValue, intValue);
