Append one file to another.

Hello.

I wonder if it is possible to append one file to another. Something like this:

FILE *text_file
FILE *aux_file;

text_file = fopen(filename, "w+");
.....
aux_file = funct_return_file();
.....

Then I would like to append aux_file to text_file

Thanks in advance for your suggestions.

if both files are just text files, which has no headers it maybe work, but if not you will have a corrupted new file ;)

Yes, they would be two simple text files.

i don't think there is a appending function... not as far as i now.
You can use fread and fwrite

Use "a" or "a+" to open a file for append.

So maybe if I use FILE *text_file as a global/extern variable, I can write to just one file from different functions instead of appending?

Better to pass it as a parameter to these functions...

And still - you need to append to "append one file to another"
