# set_file_buffer

set_file_buffer -- Sets file buffering on the given file pointer

## Description

`int fwrite`(int fp, int buffer);

set_file_buffer() sets the buffering for write operations on the given filepointer `fp` to `buffer` bytes. If `buffer` is 0 then write operations are unbuffered.

The function returns 0 on success, or EOF if the request cannot be honored.

Note that the default for any fopen with calling set_file_buffer is 8K.
