GLibfile_open_tmp

gint
g_file_open_tmp(
constgchar*tmpl,
gchar**name_used,
GError**error
)

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 NULL, 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-NULL, 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

Type: const gchar*

Template for file name, as in g_mkstemp(), basename only, or NULL for a default template.

The argument can be NULL.

The data is owned by the caller of the function.

The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows.

name_used

Type: gchar**

Location to store actual name used, or NULL.

The argument will be set by the function.

The caller of the function takes ownership of the returned data, and is responsible for freeing it.

The value is a platform-native string, using the preferred OS encoding on Unix and UTF-8 on Windows.

error

Type:

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the function if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
