You could try comparing /usr/include/asm/unistd.h on an OABI and EABI system for a start, although that will tell you nothing about which parameters have to be passed and in what way (only the syscall numbers themselves).

Can't you try to write a simple program using the functions in question and compile with "fpc -al"? That way the assembler source should show some useful information about the system calls in use.

En/na Marc Santhoff ha escrit: Can't you try to write a simple program using the functions in question and compile with "fpc -al"? the syscalls are in the rtl, so they won't show up in my program (not that I understand asm assambler, but according to http://sourceware.org/ml/libc-ports/2005-11/msg00028.html the syscall is "swi 0x0900." and there's no "swi" instruction in my code).
