    Command:

    pam_get_user

    
    
    

    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:
    
           ?   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.
    
    
    

    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.
