.SH DESCRIPTION
.sp
The \fI\%bson_context_t\fP structure is context for generation of BSON Object
IDs. This context allows overriding behavior of generating ObjectIDs. The flags
\fBBSON_CONTEXT_NONE\fP, \fBBSON_CONTEXT_THREAD_SAFE\fP, and \fBBSON_CONTEXT_DISABLE_PID_CACHE\fP
are the only ones used. The others have no effect.

.EX
#include <bson/bson.h>

int
main (int argc, char *argv[])
{
   bson_context_t *ctx = NULL;
   bson_oid_t oid;

   /* use default context, via bson_context_get_default() */
   bson_oid_init (&oid, NULL);

   /* specify a local context for additional control */
   ctx = bson_context_new (BSON_CONTEXT_NONE);
   bson_oid_init (&oid, ctx);

   bson_context_destroy (ctx);

   return 0;
