xt_ff_stdout(3) Library Functions Manual xt_ff_stdout(3) NAME xt_ff_stdout() - Create a fast file stream connected to descriptor 1 LIBRARY #include <xtend/fast-file.h> -lxtend SYNOPSIS xt_ff_t *xt_ff_stdout(void) ARGUMENTS None DESCRIPTION xt_ff_stdout(3) is a simple wrapper function for connecting file de- scriptor 1 to an xt_ff_t object using xt_ff_dopen(3). This is useful for high-performance filter programs, where using the traditional FILE *stdout would cause a bottleneck. 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 Pointer to an xt_ff_t object if successful, NULL otherwise EXAMPLES xt_ff_t *stream; // "-" as a filename argument traditionally indicates stdout if ( strcmp(argv[arg], "-") == 0 ) stream = xt_ff_stdout(); else stream = xt_ff_open(argv[arg], O_WRONLY|O_CREAT|O_TRUNC); SEE ALSO xt_ff_open(3), xt_ff_dopen(3) xt_ff_stdout(3)
