Enquire within for LP64
The program enquire.c will tell you a lot about your machine.
Here is how to compile it on HP/UX
Here is how to compile it on HP/UX
> cc +DA2.0W +w1 +M2 enquire.cA simple example that has many of the problems
Use the flags +w1 for warnings, +M2 for 64bits
These are the kind of problems you should look out for:
/714: Function "malloc" called with no prototype or definition inscope
/724: Initialization converts default int return type to pointer
/722:.*cast converts 32 bit constant to pointer
/725:.*cast converts 32 bit integer to pointer
/727:.*cast truncates pointer into 32 bit integer
/729:.*converts int* to long*
/732:.*different types treated as unsigned
/740:.*casting to a smaller size may truncate
/530:.*casting from loose to strict alignment
/720:.*Assignment may overflow
> pr -n x.cTo be continued.
