pam_get_user - get user name
Синопсис (Synopsis)
#include <security/pam_modules.h>
int pam_get_user(const pam_handle_t *pamh, const char **user,
const char *prompt);
Описание (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:
• The prompt argument passed to the function.
• What is returned by pam_get_item (pamh, PAM_USER_PROMPT, ...
);
• 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.
Возвращаемое значение (Return value)
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.
