93 * The =pam_start function creates and initializes a PAM context.
95 * The =service argument specifies the name of the policy to apply, and is
96 * stored in the =PAM_SERVICE item in the created context.
98 * The =user argument specifies the name of the target user - the user the
99 * created context will serve to authenticate.
100 * It is stored in the =PAM_USER item in the created context.
102 * The =pam_conv argument points to a =struct pam_conv describing the
103 * conversation function to use; see =pam_conv for details.
