From 2cc63358cdb0309ca996ffe56ccf402c2f2f16d5 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Wed, 20 Feb 2013 22:43:23 -0500 Subject: add mkostemp, mkstemps, and mkostemps functions and reorganize temp internals based on patch contributed by Anthony G. Basile (blueness) some issues remain with the filename generation algorithm and other small bugs, but this patch has been sitting around long enough that I feel it's best to get it committed and then work out any remaining issues. --- src/temp/mkstemp.c | 21 ++------------------- 1 file changed, 2 insertions(+), 19 deletions(-) (limited to 'src/temp/mkstemp.c') diff --git a/src/temp/mkstemp.c b/src/temp/mkstemp.c index a390d427..85764af7 100644 --- a/src/temp/mkstemp.c +++ b/src/temp/mkstemp.c @@ -1,28 +1,11 @@ -#include -#include #include -#include -#include -#include -#include #include "libc.h" -char *__mktemp(char *); +int __mkostemps(char *, int, int); int mkstemp(char *template) { - int fd, retries = 100, t0 = *template; - while (retries--) { - if (!*__mktemp(template)) return -1; - if ((fd = open(template, O_RDWR | O_CREAT | O_EXCL, 0600))>=0) - return fd; - if (errno != EEXIST) return -1; - /* this is safe because mktemp verified - * that we have a valid template string */ - template[0] = t0; - strcpy(template+strlen(template)-6, "XXXXXX"); - } - return -1; + return __mkostemps(template, 0, 0); } LFS64(mkstemp); -- cgit v1.2.1
