NAME

xt_ff_open() - Open a fast file stream for a raw or compressed file

LIBRARY

#include <xtend/fast-file.h>
-lxtend

SYNOPSIS

xt_ff_t *xt_ff_open(const char *filename, int flags)

ARGUMENTS

filename:   Name of the file to be opened
mode:       Bit mask as used by open(2)

DESCRIPTION

xt_ff_open(3) opens a raw data file using _xt_ff_raw_open(3) or a gzipped, bzipped, or xzipped file using xt_ff_popen(3), returning a pointer to a xt_ff_t stream. Must be used in conjunction with xt_ff_close(3).

The xt_ff_t system is simpler than and much faster than traditional 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 the FILE structure or NULL if open failed
