In my program I have taken one parameter in argument which I am passing to a function. before passing to it, I set a printf to check whether the argument is taken or not. it was printed properly. but when the function took it, only 3 character was taken and other chars were truncated.
ie. if I give argument “abcdef” only “abc” were taken but “def” was truncated
on argument.h file : (argument variables declared here)
unsigned char ep[32];
on main.c file :
//.....
else if (!(strcmp("-E",argv[i])))
{
if (i++==argc) stop_pgm("Argument missed for option -En");
memset(ep, '', 32);
sprintf(ep,"%s",argv[i]);
//memcpy(ep,argv[i],strlen((const char*)argv[i])+1);
i++;
continue;
}
//........
and on function.c file :
int func(void) {
/*other functions ....*/
printf("===== > EP print Flag ###### : %s", ep);
INIT_REGISTER_NSDL_ENDPOINT(endpoint_ptr, (uint8_t *) ep, ep_type, lifetime_ptr);
}
if I do not parameterize ep and not taking from argument
ie.
on function.c,
static uint8_t ep[] = {"emulation"};
It runs well. Is that due to typecasting or something else?
