PAM_GET_DATA(3)

  .SH "NAME" pam_get_data - get module internal data
  .SH "SYNOPSIS"

#include <security/pam_modules.h>

     .HP u int pam_get_data(const pam_handle_t *pamh, const char *module_data_name, const void **data);

  .SH "DESCRIPTION"

    .PP This function together with the pam_set_data(3) function is useful to manage module-specific data meaningful only to the calling PAM module.
    .PP 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.

  .SH "RETURN VALUES"

      .PP PAM_SUCCESS

               Data was successful retrieved.
