Function Documentation

istream_t* istream_fd_create	(	const char *	fname,
		int	fd,
		int	mode
	)

Creates a stream for "UNIX" file descriptor.

If fd parameters is not -1, it is used to as file descriptor for the stream and fname is used for naming the stream. Else the file is open as a regular file with fname as path.

Parameters:

fname	path of file or 0.
fd	file decriptor or -1.
mode	bit-0: read access, bit-1: write access.

Returns:

stream

Return values:

0

on error

Note:

filename is internally copied.

Even if fd is given the istream_open() must be call.

Warning:

When opening a stream with an already opened descriptor the mode should match the real open mode but since no tests are performed before calling r/w access, it should not failed in case of wrong access on given mode.
