The `pam_get_item`() function stores a pointer to the item specified by the item_type argument in the location pointed to by the item argument. The item is retrieved from the PAM context specified by the pamh argument. If `pam_get_item`() fails, the item argument is untouched.

`PAM_AUTHTOK`
  The current authentication token.
`PAM_OLDAUTHTOK`
  The expired authentication token.
`PAM_RUSER`
  The name of the applicant.
`PAM_USER_PROMPT`
  The prompt to use when asking the applicant for a user name to authenticate as.
`PAM_AUTHTOK_PROMPT`
  The prompt to use when asking the applicant for an authentication token.
`PAM_OLDAUTHTOK_PROMPT`
  The prompt to use when asking the applicant for an expired authentication token prior to changing it.
`PAM_HOST`
  The name of the host the application runs on.
`PAM_SOCKADDR`
  The sockaddr_storage of the applicants's host.
