Is there a length limit for name_value string in pam_putenv(pamh, name_value) ?

[Andy]

Hi all,

            #include <security/pam_appl.h>

            int pam_putenv (pamh, name_value);

            pam_handle_t *pamh;
            const char *name_value;

In the PAM writers' guide, I saw a description for this method, but
did not see any length restriction for name_value, does that mean
there is no length limit for string "name_value" ?


Thanks.
