From 642b9b4fab0fcba77ed4bc596c4adc92ae0f13c3 Mon Sep 17 00:00:00 2001 From: Joel Hestness Date: Sat, 27 Dec 2014 13:48:40 -0600 Subject: [PATCH] syscall_emul: Return correct writev value According to Linux man pages, if writev is successful, it returns the total number of bytes written. Otherwise, it returns an error code. Instead of returning 0, return the result from the actual call to writev in the system call. --- src/sim/syscall_emul.hh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/sim/syscall_emul.hh b/src/sim/syscall_emul.hh index a4f9b238e..0c06a5147 100644 --- a/src/sim/syscall_emul.hh +++ b/src/sim/syscall_emul.hh @@ -1138,7 +1138,7 @@ writevFunc(SyscallDesc *desc, int callnum, LiveProcess *process, if (result < 0) return -errno; - return 0; + return result; } -- 2.30.2
