Did you just calculate how much functions it would take to support all these combinations besides the fact that no kernel function takes e.g. floats. > 3.

Did you realize that the linux supports _only_ one calling convention: taking the syscall number in a register and the other parameters in the remaining six registers? > > 1. Is there a way to implement the above with array of const ? Just add typecasts and a wrapper. Array of const is slow and not suitable for such low level stuff. > 2. Is there a way to implement the above without using assembly, Just add type casts. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
