pub fn mkstemp<P: AsRef<Path>>(tmpl: P) -> i32Expand description
Opens a temporary file. See the mkstemp() documentation
on most UNIX-like systems.
The parameter is a string that should follow the rules for
mkstemp() templates, i.e. contain the string “XXXXXX”.
mkstemp() is slightly more flexible than mkstemp() in that the
sequence does not have to occur at the very end of the template.
The X string will be modified to form the name of a file that
didn’t exist. The string should be in the GLib file name encoding.
Most importantly, on Windows it should be in UTF-8.

template filename
Returns
A file handle (as from open()) to the file
opened for reading and writing. The file is opened in binary
mode on platforms where there is a difference. The file handle
should be closed with close(). In case of errors, -1 is
returned and errno will be set.
