==Definition==
'''INT''' fread ( <'''INT''' handle> , data )

Reads the information from a file loaded with [[fopen]] to a variable.

== Parameters ==
{|
| '''INT''' handle || - Identifier of the file loaded with [[fopen]].
|-
| data || - The data to read from the file (can be any type of variable that Fenix supports).
|}

== Returns ==
Data
{|
| -1 || - Could not read?
|-
| !-1 || - The data read from the file (can be any type of variable that Fenix supports).
|}

== Example ==
<pre>
Process readthing(STRING loadpath);
Private
handle; // handle for the loaded file
druppels; // here's where the loaded data go

Begin

handle=fopen(loadpath,O_READ); // opens the file in reading mode
fread(handle,druppels); // reads from the file and puts the data in druppels
fclose(handle); // zipping up after business is done

write_int(0,160,100,4,&druppels); // let's see what we got here

End

</pre>
Used in example: [[fopen]], [[fclose]], [[write_int]]
