Scanset

[lezard]

I can't find a good charset for my string.
The separator is ':' :-(

Look at this code

int main()
{
char *str = "titititi:tutu: toto\n";
char buf1[64];
char buf2[64];
char buf3[64];

sscanf(str, "%64s[:]%64s[:]%64s[\n]", buf1, buf2, buf3);
printf("buf1: %s\n", buf1);
printf("buf2: %s\n", buf2);
printf("buf3: %s\n", buf3);
}

I would like to have tititi in buf1, tutu in buf2 and toto in buf3
But with this scanset It doesn't work. I have tried
"%64s%*[:]%64s%*[:]%64s%*[\n]" and It doesn't work too.

Could someone help me? :]

int main(void)
{
char *str = "titititi:tutu: toto\n";
char buf1[64];
char buf2[64];
char buf3[64];

sscanf(str, "%64[^:]%*[:]%64[^:]%*[:]%64[^\n]", buf1, buf2, buf3);
printf("buf1: %s\n", buf1);
printf("buf2: %s\n", buf2);
printf("buf3: %s\n", buf3);
return 0;
}

ITYM "63" for each "64". Also, the format can be
simplified a bit:

sscanf(str, "%63[^:]:%63[^:]:%63[^\n]", ...

buf3);

Note you should check the return value of sscanf. For instance, the
string "a::c" will put "a" into buf1, and "c" into buf2, with sscanf
returning 2, leaving the contents of buf3 unspecified. You also have
an off by 1 error.

You can also simplify by matching the colons directly...

r = sscanf(str, "%63[^:\n]:%63[^:\n]:%63[^\n]", buf1, buf2, buf3);

I think so too.

Many people would like to see all titis in the buf. Those with
tutus are innately not in the buf, and I think toto would bark if
so confined. Meanwhile you are offending the prudes :-)
