pthread_attr_init: default value of inhertished flag

Hi,
according to the man pages, the default value for the inheritsched
flag sholud be
PTHREAD_EXPLICIT_SCHED, while a call to pthread_attr_init returns
PTHREAD_INHERIT_SCHED.
This is due to the pthread_attr_init that memset to 0 all the
pthread_attr struct
and the bit ATTR_FLAG_NOTINHERITSCHED is not set in the flags field.

Looking at the POSIX standard, the default value is "unspecified"...
so what is the correct
value defined by glibc/Linux ? is the man page wrong or is it a bug into glibc?

Best regards,
Carmelo
