From 880cd5dd2040826b8a1c49ecf59a385ea775a3d3 Mon Sep 17 00:00:00 2001 From: Daniel Stenberg Date: Mon, 25 Feb 2019 18:12:51 +0100 Subject: strerror: make the strerror function use local buffers Instead of using a fixed 256 byte buffer in the connectdata struct. In my build, this reduces the size of the connectdata struct by 11.8%, from 2160 to 1904 bytes with no functionality or performance loss. This also fixes a bug in schannel's Curl_verify_certificate where it called Curl_sspi_strerror when it should have called Curl_strerror for string from GetLastError. the only effect would have been no text or the wrong text being shown for the error.
