GLib.mkstemp_full

function mkstemp_full(tmpl: String, flags: Number(gint), mode: Number(gint)): Number(gint) {
    // Gjs wrapper for g_mkstemp_full()
}

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". GLib.mkstemp_full is slightly more flexible than mkstemp() in that the sequence does not have to occur at the very end of the template and you can pass a mode and additional flags. 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.

Since 2.22
