__install_dev_full

Syntax

#include <sys/xdevices.h> int __install_dev_full (void);

Description

This function activates support for the special file `/dev/full'. When read, `dev/full' always returns `\0' characters. Writes to `/dev/full' will fail with errno set to ENOSPC. Seeks on `/dev/full' always succeed.

The DJGPP debug support functions will interfere with `/dev/full' (see section File System Extensions).

Return Value

On success, a non-zero value is returned; on failure, zero is returned.
