From 0f8a6ff0ed7c57c636b79d8a7a9a78da837d763a Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Thu, 28 Jul 2005 03:34:44 +0000 Subject: Add a config option for abort() to shutdown the stdio subsystem. This is mainly to cut down on noise in the NIST/PCTS tests since older POSIX behavior was to fclose() (and hence fflush()) all open streams. --- extra/Configs/Config.in | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'extra') diff --git a/extra/Configs/Config.in b/extra/Configs/Config.in index 743c3f554..4cb4216bb 100644 --- a/extra/Configs/Config.in +++ b/extra/Configs/Config.in @@ -775,10 +775,11 @@ config UCLIBC_PRINTF_SCANF_POSITIONAL_ARGS config UCLIBC_HAS_SCANF_GLIBC_A_FLAG - bool "Support glibc's 'a' flag for scanf string conversions" + bool "Support glibc's 'a' flag for scanf string conversions (not implemented)" default n help NOTE!!!
