SYNOPSIS
.In sys/types.h
.In security/pam_appl.h "int" pam_get_authtok "pam_handle_t *pamh" "int item" "const char **authtok" "const char *prompt"
DESCRIPTION
The pam_get_authtok function returns the cached authentication token, or prompts the user if no token is currently cached. Either way, a pointer to the authentication token is stored in the location pointed to by the authtok argument. The item argument must have one of the following values: | PAM_AUTHTOK | | | Returns the current authentication token, or the new token when changing authentication tokens. | | PAM_OLDAUTHTOK | | | Returns the previous authentication token when changing authentication tokens. | |
The prompt argument specifies a prompt to use if no token is cached. If it is NULL, the PAM_AUTHTOK_PROMPT or PAM_OLDAUTHTOK_PROMPT item, as appropriate, will be used. If that item is also NULL, a hardcoded default prompt will be used. If item is set to PAM_AUTHTOK and there is a non-null PAM_OLDAUTHTOK item, pam_get_authtok will ask the user to confirm the new token by retyping it. If there is a mismatch, pam_get_authtok will return PAM_TRY_AGAIN.
RETURN VALUES
The pam_get_authtok function returns one of the following values: | [PAM_BUF_ERR] | | | Memory buffer error. | | [PAM_CONV_ERR] | | | Conversation failure. | | [PAM_SYSTEM_ERR] | | | System error. | | [PAM_TRY_AGAIN] | | | Try again. | |
