I'm tracking down a stupid computer bug. I'm just sort of curious why
'/0' string won't show up after I add it. Here is the code snippet
void *allocate_string_array(size_t len, char *line, char **strarr)
{
int count = 0;
if( (len+1) < MAXLINE) {
if((strarr=malloc(sizeof(line) + 1)) == NULL){
return NULL;
}
strarr[count] = dupstr(line);
}
else {
fprintf(stderr, "Input line is too long \n");
exit(EXIT_FAILURE);
}
*(strarr+len+1)='\0';
return *strarr;
}
When I first enter the function
(gdb) print *strarr
$4 = 0x0
(gdb) print line
$5 = 0x804a180 "this is a really long long line\n"
Right after I leave the function
(gdb) step
120 return *strarr;
(gdb) print line
$6 = 0x804a180 "this is a really long long line\n"
(gdb) print *strarr
$7 = 0x840a180 "this is a really long long line\n"
(gdb)
My brain doesn't always function correctly after I've worked 14 hours.
should have been
However, my compiler didn't bitch about the typo. Here is what happens when I turn on full warnings.
[cda@localhost ~]$ gcc -g -Wall -ansi -Werror -pedantic x_tty.c -o x_tty
[cda@localhost ~]$
Now what does
What is "*(strarr+len+1)='\0';" trying to do?
It's just any ugly hack because I was getting some funky output. I figured the reason why I was getting funky stuff was because my string wasn't terminated. However, it only works half the time. I still somethines get
now
is a really long long line
