From 4db007c3b1b8f793efecd4b4ac046147ee0d2485 Mon Sep 17 00:00:00 2001 From: Don Cross Date: Sat, 1 Aug 2015 18:34:54 -0400 Subject: encode() now returns error code if save_file() cannot open output file. Before this change, encode() would return 0 whether or not the output file was created. There was no way for a caller to know when the file could not be created (e.g. due to a non-existent parent directory). Changed save_file() to return error 79 if it cannot open output file. encode() checks return code from save_file() and passes any error value back to the caller. --- lodepng.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lodepng.h') diff --git a/lodepng.h b/lodepng.h index 74e4495..e68d40b 100644 --- a/lodepng.h +++ b/lodepng.h @@ -855,7 +855,7 @@ void load_file(std::vector& buffer, const std::string& filename); Save the binary data in an std::vector to a file on disk.
