pam_get_user

PAM_GET_USER(3) 					   BSD Library Functions Manual 					   PAM_GET_USER(3)

NAME

     pam_get_user -- retrieve user name

LIBRARY

     Pluggable Authentication Module Library (libpam, -lpam)

SYNOPSIS

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

     int
     pam_get_user(pam_handle_t *pamh, const char **user, const char *prompt);

DESCRIPTION

     The pam_get_user function returns the name of the target user, as specified to pam_start(3).  If no user was specified, nor set using
     pam_set_item(3), pam_get_user will prompt for a user name.  Either way, a pointer to the user name is stored in the location pointed to by
     the user argument.

     The prompt argument specifies a prompt to use if no user name is cached.  If it is NULL, the PAM_USER_PROMPT item will be used.  If that item
     is also NULL, a hardcoded default prompt will be used.  Either way, the prompt is expanded using openpam_subst(3) before it is passed to the
     conversation function.

     If pam_get_user is called from a module and the user_prompt option is set in the policy file, the value of that option takes precedence over
     both the prompt argument and the PAM_USER_PROMPT item.

RETURN VALUES

     The pam_get_user function returns one of the following values:

     [PAM_BUF_ERR]	 Memory buffer error.

     [PAM_CONV_ERR]	 Conversation failure.

     [PAM_SYSTEM_ERR]	 System error.

SEE ALSO

     openpam_subst(3), pam(3), pam_get_authtok(3), pam_get_item(3), pam_set_item(3), pam_start(3), pam_strerror(3)
