how to use "goto" with different file.

[eexpress]

i had a label 'SYS_RST'; within main.c.

now want using 'goto SYS_RST' within rtc.c.

how can i define the SYS_RST in my rtc.c file. such as:
extern const *(void *) & SYS_RST;

plz help me.

for this is some special condition i must use this 'goto'. and i had search in CW's complie manual, but no answer.

if some advice, also can directlly send a message to exp.exp,gmail,com.

thanks

You cannot use the ANSI-C goto to jump across functions.
Does the ANSI-C longjmp work for your problem? Otherwise real assembly?
Maybe we can help if you let us know the problem you try to solve so we see why a normal function call does not work for your case.

the reason is with some special conditions, my chips need partly reset. that' say just need jump to the location after CGM_Ini(). and all other steps such as initilize datas need be operated.
so i using a label called SYS_RST after CGM_Ini(). and want get the absolute address of SYS_RST. so i can directlly jump to here.

of course i can set a flag when meet the special conditions in other c file, and within my main() i judge this flag and jump to SYS_RST.

but really i want know if i can using a assembler way to do this. so if i can find how to define the label as a absolute address. i can using "asm jmp xxxxx".

thanks

longjmp() would probably work, yes.

But since that is sort of quick & dirty, perhaps you could concider a different design? Something like this perhaps:

int main()
{
init_out_of_reset();

for( ;; )
{
init_some_more();

while(everything == OK)
{
...

if(weird_error)
everything = NOT_OK;
}



}
