From d25493587595a7bc5eb0764dad9e8de10a26a854 Mon Sep 17 00:00:00 2001 From: "Roberto E. Vargas Caballero" Date: Wed, 12 Sep 2012 21:51:55 +0200 Subject: Remove buffering to fileio instead of calling fflush By default text files are line buffered, and this means that -f option will not write the line until a \n is printed. This is not very useful for debugging, so a call to fflush was added. This patch substitute this call (which will be done by each character painted) by the full remove of the buffering in the file. --- st.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) --- st.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-) diff --git a/st.c b/st.c index 8741145..19d0a86 100644 --- a/st.c +++ b/st.c @@ -355,7 +355,7 @@ static STREscape strescseq; static int cmdfd; static pid_t pid; static Selection sel; -static FILE *fileio; +static int iofd = -1; static char **opt_cmd = NULL; static char *opt_io = NULL; static char *opt_title = NULL; @@ -821,9 +821,9 @@ ttynew(void) { signal(SIGCHLD, sigchld); if(opt_io) { if(!strcmp(opt_io, "-")) { - fileio = stdout; + iofd = STDOUT_FILENO; } else { - if(!(fileio = fopen(opt_io, "w"))) { + if((iofd = open(opt_io, O_WRONLY | O_CREAT, 0666)) < 0) { fprintf(stderr, "Error opening %s:%s\n", opt_io, strerror(errno)); } @@ -1599,10 +1599,8 @@ void tputc(char *c) { char ascii = *c; - if(fileio) { - putc(ascii, fileio); - fflush(fileio); - } + if(iofd != -1) + write(iofd, c, 1); if(term.esc & ESC_START) { if(term.esc & ESC_CSI) { -- cgit v1.2.3
