PAM_SET_DATA(3)          BSD Library Functions Manual          PAM_SET_DATA(3)

NAME
     pam_set_data -- set module information

LIBRARY
     Pluggable Authentication Module Library (libpam, -lpam)

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

     int
     pam_set_data(pam_handle_t *pamh, const char *module_data_name, void *data,
         void (*cleanup)(pam_handle_t *pamh, void *data, int pam_end_status));

DESCRIPTION
     The pam_set_data function associates a pointer to an opaque object with an arbitrary string specified
     by the module_data_name argument, in the PAM context specified by the pamh argument.

     If not NULL, the cleanup argument should point to a function responsible for releasing the resources
     associated with the object.

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

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

     [PAM_BUF_ERR]       Memory buffer error.

     [PAM_SYSTEM_ERR]    System error.

SEE ALSO
     pam(3), pam_get_data(3), pam_strerror(3)
