Scanf and wildcard

[raphfrk]

I have a string that I want to extract some fields out of.

For example

ZABDE10FGH20
ZFDSF11FGG21
(etc)

I might want to extract the 2 sets of numbers.

One option would be to use throwaway buffers.

char buffer1[6];
int num1;
char buffer[4];
int num2;

and then use

fscanf( fp , "%5s%2d%3s%d" , buffer1, num1 , buffer2, num2 );

Is there a better way to get scanf to skip lines other than having it
write them to an unused buffer ?

you can discard the matched result by using `*'.
Ie:
scanf("%*s%s", buf);

with input:
hello world

would read `world' into the buffer.

Yikes! scanf("%s") should not be used without a length qualifier,
otherwise it is effectively gets().

Don't worry. buf is long enough

That's just hilarious Fancy reading that
excuse as a comment in some core system.

How did you manage to define an infinitely large buf?
