SYNOPSIS

          #include <bson/bson.h>

          typedef enum {
            BSON_CONTEXT_NONE = 0,
            BSON_CONTEXT_DISABLE_PID_CACHE = (1 << 2),
          } bson_context_flags_t;

          typedef struct _bson_context_t bson_context_t;

          bson_context_t *
          bson_context_get_default (void);
          bson_context_t *
          bson_context_new (bson_context_flags_t flags);
          void
          bson_context_destroy (bson_context_t *context);

DESCRIPTION

       The  bson_context_t  <>  structure  is  context  for  generation  of BSON Object IDs. This context allows
       overriding behavior of generating ObjectIDs. The flags BSON_CONTEXT_NONE,  BSON_CONTEXT_THREAD_SAFE,  and
       BSON_CONTEXT_DISABLE_PID_CACHE are the only ones used. The others have no effect.

EXAMPLE

          #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;
          }
