IN: BHL = pointer to null-terminated filename (B = 0, local) CDE = pointer to null-terminated arguments string, optional (C = 0, local) A = execution mode (A0=0: execute, A0=1:debug) OUT: Fc = 0, successfulsuccess Fc = 1, failure and A = error Registers affected after return: AFBCDEHL depends on ELF execution IXIY changed by the call |
Notes
...
If the program has no need of arguments, simply let CDE point to a null-terminator (0).
Arguments in the argument string are space separated, this string is null terminated.
Arguments passing to ELF program is performed by this call. Arguments are pushed to the stack The call push the arguments from right to left according SDCC convention.
