pam_get_user - get user name

The pam_get_user function returns the name of the user specified by pam_start(3). If no user was specified it returns 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.
