SYNOPSIS


.In sys/types.h
.In 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 will be used. If that item is also NULL, a hardcoded default prompt will be used.

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.
