get_fmt_args()

def miasm.os_dep.linux_stdlib.get_fmt_args	(		jitter,
			fmt,
			cur_arg
	)

Here is the caller graph for this function:

xxx___libc_start_main()

def miasm.os_dep.linux_stdlib.xxx___libc_start_main

(

)

Basic implementation of __libc_start_main

int __libc_start_main(int *(main) (int, char * *, char * *), int argc,
                      char * * ubp_av, void (*init) (void),
                      void (*fini) (void), void (*rtld_fini) (void),
                      void (* stack_end));

Note:
 - init, fini, rtld_fini are ignored
 - return address is forced to ABORT_ADDR, to avoid calling abort/hlt/...
 - in powerpc, signature is:

int __libc_start_main (int argc, char **argv, char **ev, ElfW (auxv_t) *
                   auxvec, void (*rtld_fini) (void), struct startup_info
                   *stinfo, char **stack_on_entry)
