gnutls_transport_set_global_errno — API function
#include <gnutls/gnutls.h>
void
gnutls_transport_set_global_errno( |
int | err); |
Store err in the
global errno variable. Useful values for err is EAGAIN and EINTR, other
values are treated will be treated as real errors in the
push/pull function.
This function is useful in replacement push/pull functions
set by gnutls_transport_set_push_function and
gnutls_transport_set_pullpush_function under Windows, where
the replacement push/pull may not have access to the same
errno variable that is used by
GnuTLS (e.g., the application is linked to msvcr71.dll and
gnutls is linked to msvcrt.dll).
Whether this function is thread safe or not depends on
whether the global variable errno is thread safe, some system
libraries make it a thread−local variable. When
feasible, using the guaranteed thread−safe gnutls_transport_set_errno() may be
better.
