[Pkg-gnutls-maint] Bug#409778: libgnutls-dev: warnings when compiling sample Posix threading code

[Russell Coker]

Package: libgnutls-dev
Version: 1.4.4-3
Severity: normal

#include <gnutls/gnutls.h>
#include <gcrypt.h>
#include <errno.h>
#include <pthread.h>
GCRY_THREAD_OPTION_PTHREAD_IMPL;

int main()
{
  /* The order matters.
   */
  gcry_control (GCRYCTL_SET_THREAD_CBS, &gcry_threads_pthread);
  gnutls_global_init();
}

The above is from /usr/share/doc/gnutls-doc/html/gnutls.html.  I compile it
with the following command and get warnings as below:

gcc test.cpp -lstdc++ -lgnutls -W -lpthread
test.cpp:9: warning: missing initializer for member ‘gcry_thread_cbs::read’
test.cpp:9: warning: missing initializer for member ‘gcry_thread_cbs::write’
test.cpp:9: warning: missing initializer for member ‘gcry_thread_cbs::select’
test.cpp:9: warning: missing initializer for member ‘gcry_thread_cbs::waitpid’

The GCRY_THREAD_OPTION_PTHREAD_IMPL macro doesn't initialise all members of
gcry_thread_cbs.  I believe that the sample code should compile with no
warnings and that the fields in question should be initialised to NULL or
a reduced structure that lacks those fields should be used.
