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.

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.
