I'm sure the ABI > explicitly says what lseek() takes for arguments, for example. The SVR4 ABI specification doesn't say anything about system calls -- it just specifies what libc has to provide. (Actually in my old printed copy of the spec, they call the system interface library "libsys".) The library has to provide a certain kind of lseek(), for example, but the ABI standard says nothing about how that is implemented lower down. John -- John Polstra jdp@polstra.com John D.
