Subject: pthread_atfork: fix return value on malloc failure
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=377218cb963aa20c6eb91781b0c79ad606631e6f;p=musl

pthread_atfork: fix return value on malloc failure

POSIX requires pthread_atfork to report errors via its return value,
not via errno. The only specified error is ENOMEM.
