+/**
+ * g_creat:
+ * @filename: a pathname in the GLib file name encoding
+ * @mode: as in creat()
+ *
+ * A wrapper for the POSIX creat() function. The creat() function is
+ * used to convert a pathname into a file descriptor, creating a file
+ * if necessar. Note that on POSIX systems file descriptors are
+ * implemented by the operating system. On Windows, it's the C library
+ * that implements creat() and file descriptors. The actual Windows
+ * API for opening files is something different.
+ *
+ * See the C library manual for more details about creat().
+ *
+ * Returns: a new file descriptor, or -1 if an error occurred. The
+ * return value can be used exactly like the return value from creat().
+ * 
+ * Since: 2.7
