SYNOPSIS

ffile_t *ffdopen(int fd, int flags)

ARGUMENTS
fd          Open file descriptor to which stream is attached
flags       Bit flags passed to open(3)

DESCRIPTION
ffdopen() initializes a ffile_t stream, much as fdopen() does for a FILE stream. Unlike fdopen(), ffdopen() takes the same bit mask argument as open() to determine the open mode. See open(3) for details. An optimally sized buffer for the underlying filesystem is allocated, along with additional space for limited ffungetc() operations. The ffile_t system is simpler than and several times as fast as FILE on typical systems. It is intended for processing large files character-by-character, where low-level block I/O is not convenient, but FILE I/O causes a bottleneck.

RETURN VALUES
A pointer to a ffile_t object on success, NULL on failure

EXAMPLES
ffile_t *stream;
char    *filename;
int     fd;
fd = open(filename, O_RDONLY);
stream = ffdopen(fd, O_RDONLY);
