write to .txt file in columns

[Seron]

How could I write to a text file so that it appears in column format? This is for a .log file.

It should look something like this:

<date>		<address>	<file>
021125		11.34.56.156	/thisdir/thisfile
021126		5.12.15.12	/thatdir/thatfile
....

Is there a function for this or do I need to write one?

Thanks in advance,

Seron

Yes there is a function: fprintf (read the - (negative) flag)

[Vber]

fprintf(fp,"%s\t%d\t%d\n",nm,level,points);
This is an example

I think, this should work.

A tab doesn't always work.

What about a normal fprintf with - (negative flag)?

printf("[%-20s] [%-20s] [%-20s]\n", "aaa", "aaaaaa", "a");
printf("[%-20s] [%-20s] [%-20s]\n", "bbbbbbbbbb", "b", "bbbbb");

Output:

[aaa                 ] [aaaaaa              ] [a                   ]
[bbbbbbbbbb          ] [b                   ] [bbbbb               ]
