PAM_GET_DATA(3)          BSD Library Functions Manual          PAM_GET_DATA(3)

NAME
     pam_get_data -- get module information

LIBRARY
     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS
     #include <sys/types.h>
     #include <security/pam_appl.h>

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

DESCRIPTION
     The pam_get_data function looks up the opaque object associated with the
     string specified by the module_data_name argument, in the PAM context
     specified by the pamh argument.  A pointer to the object is stored in the
     location pointed to by the data argument.

     This function and its counterpart pam_set_data(3) are useful for managing
     data that are meaningful only to a particular service module.

RETURN VALUES
     The pam_get_data function returns one of the following values:

     [PAM_NO_MODULE_DATA]
                         Module data not found.

     [PAM_SYSTEM_ERR]    System error.
