xt_ff_putc(3) Library Functions Manual xt_ff_putc(3) NAME xt_ff_putc() - Write a character to a fast file stream LIBRARY #include <xtend/fast-file.h> -lxtend SYNOPSIS inline int xt_ff_putc(xt_ff_t *stream, int ch) ARGUMENTS ch Character to write to stream stream Pointer to an xt_ff_t object opened by xt_ff_open(3) DESCRIPTION xt_ff_putc(3) writes a single character to a xt_ff_t stream opened by xt_ff_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 character written, or EOF if unable to write 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_puts(ch, outstream); xt_ff_close(instream); xt_ff_close(outstream); SEE ALSO xt_ff_open(3), xt_ff_getc(3), xt_ff_close(3) xt_ff_putc(3)
