void lwp_perror(s) char *s;
char **lwp_errstr();
When a primitive fails (returns -1), lwp_geterr() can be used to obtain the identity of the error (which is part of the context for each lwp). lwp_perror() can be used to print an error message on the standard error file (analogous to perror.3 when a lwp primitive returns an error indication. lwp_perror() uses the same mechanism as lwp_geterr() to obtain the last error. lwp_errstr returns a pointer to the (NULL-terminated) list of error messages.
lwp_libcset (see lwp_ctxinit.3l allows errno from the standard C library reflect a per-thread value rather than a per-pod value.
