av_warn_unused_result int avpriv_open	(	const char *	filename,
		int	flags,
			...
	)

avpriv_fopen_utf8()

FILE* avpriv_fopen_utf8	(	const char *	path,
		const char *	mode
	)

Open a file using a UTF-8 filename.

avpriv_tempfile()

int avpriv_tempfile	(	const char *	prefix,
		char **	filename,
		int	log_offset,
		void *	log_ctx
	)

Wrapper to work around the lack of mkstemp() on mingw.

Also, tries to create file in /tmp first, if possible. *prefix can be a character constant; *filename will be allocated internally.

Returns

file descriptor of opened file (or negative value corresponding to an AVERROR code on error) and opened file name in **filename.

Note

On very old libcs it is necessary to set a secure umask before calling this, av_tempfile() can't call umask itself as it is used in libraries and could interfere with the calling application.
