xt_ffopen(3)

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

SYNOPSIS

ffile_t *xt_ffopen(const char *filename, int flags)

ARGUMENTS
filename:   Name of the file to be opened
mode:       "r" or "w", passed to fopen() or popen()

DESCRIPTION
xt_ffopen(3) opens a raw data file using fopen() or a gzipped, bzipped, or xzipped file using popen(), returning a pointer to a ffile_t stream. Must be used in conjunction with xt_ffclose() to ensure that ffclose() or ffpclose() is called where appropriate. 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 the FILE structure or NULL if open failed
