PAM_GET_USER(3) Linux-PAM Manual PAM_GET_USER(3)
NAME
pam_get_user - get user name
SYNOPSIS
#include <security/pam_modules.h>
int pam_get_user(const pam_handle_t *pamh, const char **user,
const char *prompt);
DESCRIPTION
The pam_get_user function returns the name of the user specified by
pam_start(3). If no user was specified it what pam_get_item (pamh,
PAM_USER, ... ); would have returned. If this is NULL it obtains the
username via the pam_conv(3) mechanism, it prompts the user with the
first non-NULL string in the following list:
o The prompt argument passed to the function.
o What is returned by pam_get_item (pamh, PAM_USER_PROMPT, ... );
o The default prompt: "login: "
By whatever means the username is obtained, a pointer to it is returned
as the contents of *user. Note, this memory should not be free()'d or
modified by the module.
This function sets the PAM_USER item associated with the
pam_set_item(3) and pam_get_item(3) functions.
RETURN VALUES
PAM_SUCCESS
User name was successful retrieved.
PAM_SYSTEM_ERR
A NULL pointer was submitted.
PAM_CONV_ERR
The conversation method supplied by the application failed to
obtain the username.
