pam_get_data - get module internal data
Contents
Description
This function together with the pam_set_data(3) function is useful to manage module-specific data
meaningful only to the calling PAM module.
The pam_get_data function looks up the object associated with the (hopefully) unique string
module_data_name in the PAM context specified by the pamh argument. A successful call to pam_get_data
will result in data pointing to the object. Note, this data is not a copy and should be treated as
constant by the module.
