int avpriv_open ( const char *  filename,
int  flags,

A wrapper for open() setting O_CLOEXEC.

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.

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