From c8c0844f7fbcb955848ca84432e5ffcf71f1cef1 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Fri, 2 Aug 2013 12:59:45 -0400 Subject: debloat code that depends on /proc/self/fd/%d with shared function I intend to add more Linux workarounds that depend on using these pathnames, and some of them will be in "syscall" functions that, from an anti-bloat standpoint, should not depend on the whole snprintf framework. --- src/process/fexecve.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'src/process') diff --git a/src/process/fexecve.c b/src/process/fexecve.c index 5939181a..8ab02a74 100644 --- a/src/process/fexecve.c +++ b/src/process/fexecve.c @@ -2,11 +2,12 @@ #include #include +void __procfdname(char *, unsigned); + int fexecve(int fd, char *const argv[], char *const envp[]) { - static const char proc[] = "/proc/self/fd/%d"; - char buf[sizeof proc + 3*sizeof(int)]; - snprintf(buf, sizeof buf, proc, fd); + char buf[15 + 3*sizeof(int)]; + __procfdname(buf, fd); execve(buf, argv, envp); if (errno == ENOENT) errno = EBADF; return -1; -- cgit v1.2.1
