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/##.
