pub fn file_open_tmp(
tmpl: Option<impl AsRef<Path>>,
) -> Result<(RawFd, PathBuf), Error>Expand description
Opens a file for writing in the preferred directory for temporary files (as returned by g_get_tmp_dir()).
@tmpl should be a string in the GLib file name encoding containing
a sequence of six ‘X’ characters, as the parameter to g_mkstemp().
However, unlike these functions, the template should only be a
basename, no directory components are allowed. If template is
None, a default template is used.
Note that in contrast to g_mkstemp() (and mkstemp()) @tmpl is not modified, and might thus be a read-only literal string.
Upon success, and if @name_used is non-None, the actual name used
is returned in @name_used. This string should be freed with g_free()
when not needed any longer. The returned name is in the GLib file
name encoding.
§tmpl
Template for file name, as in
g_mkstemp(), basename only, or None for a default template
§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 @error will be set.
§name_used
location to store actual name used,
or None
