From a14e2d9dfe0bc17800a5ab6b0439a3db50702586 Mon Sep 17 00:00:00 2001 From: Bodo Möller Date: Thu, 24 Jan 2002 16:16:43 +0000 Subject: New functions ERR_peek_last_error ERR_peek_last_error_line ERR_peek_last_error_line_data (supersedes ERR_peek_top_error). Rename OPENSSL_NO_OLD_DES_SUPPORT into OPENSSL_DISABLE_OLD_DES_SUPPORT because OPENSSL_NO_... indicates disabled algorithms (according to mkdef.pl). --- crypto/bio/bss_file.c | 2 +- crypto/conf/conf_def.c | 2 +- crypto/conf/conf_mall.c | 18 +++++++++++++----- crypto/des/des.h | 2 +- crypto/err/err.c | 47 +++++++++++++++++++++++++++++++---------------- crypto/err/err.h | 9 ++++++--- 6 files changed, 53 insertions(+), 27 deletions(-) (limited to 'crypto') diff --git a/crypto/bio/bss_file.c b/crypto/bio/bss_file.c index e3af936374..8b3ff278d9 100644 --- a/crypto/bio/bss_file.c +++ b/crypto/bio/bss_file.c @@ -103,7 +103,7 @@ BIO *BIO_new_file(const char *filename, const char *mode) { SYSerr(SYS_F_FOPEN,get_last_sys_error());
