_xt_ff_raw_close(3) Library Functions Manual _xt_ff_raw_close(3) NAME _xt_ff_raw_close() - Close a stream created by _xt_ff_raw_open() LIBRARY #include <xtend/fast-file.h> -lxtend SYNOPSIS int _xt_ff_raw_close(xt_ff_t *stream) ARGUMENTS stream Pointer to an xt_ff_t object opened by xt_ff_open(3) DESCRIPTION _xt_ff_raw_close(3) closes a xt_ff_t stream opened by _xt_ff_raw_open(3). It writes out any remaining data in the output buffer, deallocates memory allocated by xt_ff_open(3), and closes the underlying file descriptor opened by open(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 The return status of the underlying close(3) call EXAMPLES char *infilename, *outfilename; xt_ff_t *instream, *outstream; int ch; if ( (instream = xt_ff_open(infilename, O_RDONLY)) == NULL ) { fprintf(stderr, "Cannot open %s for reading.n", infilename); exit(EX_NOINPUT); } if ( (outstream = xt_ff_open(outfilename, O_WRONLY|O_CREAT|O_TRUNC)) == NULL ) { fprintf(stderr, "Cannot open %s for writing.n", outfilename); exit(EX_NOINPUT); } while ( (ch = xt_ff_getc(stream)) != EOF ) xt_ff_putc(ch, outstream); xt_ff_close(instream); xt_ff_close(outstream); SEE ALSO xt_ff_open(3), xt_ff_getc(3), xt_ff_putc(3) _xt_ff_raw_close(3)
