We sending data over UDP from the iPhone, sometimes, but not always, in response to our first send() of UDP data, we are getting back a -1 return code and errno set to 1 (EPERM / operation not permitted). The EPERM result for send(), sendto() and sendmsg() is not documented in the man pages as a return result from those functions.
Has anyone out there encountered this and might be able to shed some light on what this errno value means in this context?
