fprocopen - stream open functions on files below /proc/##
#define _GNU_SOURCE
#include <stdio.h>
#include <proc/procio.h>
FILE *fprocopen(const char *path, const char *mode);
The fprocopen function opens files below /proc/## whose name is
the string to by path and associates a stream with it. The
argument mode points to a string containing one of the following
sequences
r Open a file below /proc/## for reading even large buffers.
The stream is positioned at the beginning of the file.
w[<del>]
Open a file below /proc/## for writing even large buffers.
The optional delimiter character can be one of the
follwoing ' ', ',', '.', and ':' where the default is the
comma ','. This allows to split very large input lines
into pieces at this delimiter and write each of them to
the opened file below /proc/##.
e The underlying file descriptor will be closed if you use
any of the `exec...' functions within your code.
The internal API allows the use of stdio functions to read and
write large buffers below /proc/##.
