14 * This file implements a configuration backend for text files. All the
15 * configuration information is stored in a text file that uses a format
16 * described in the sample configuration file, wpa_supplicant.conf.
25 #include "eap_peer/eap_methods.h"
29 * wpa_config_get_line - Read the next configuration file line
30 * @s: Buffer for the line
31 * @size: The buffer length
32 * @stream: File stream to read from
33 * @line: Pointer to a variable storing the file line number
34 * @_pos: Buffer for the pointer to the beginning of data on the text line or
35 * %NULL if not needed (returned value used instead)
36 * Returns: Pointer to the beginning of data on the text line or %NULL if no
37 * more text lines are available.
39 * This function reads the next non-empty line from the configuration file and
40 * removes comments. The returned string is guaranteed to be null-terminated.
