DESCRIPTION

33       The  bson_context_t  structure is context for generation of BSON Object
34       IDs. This context allows for specialized overriding  of  how  ObjectIDs
35       are generated based on the applications requirements. For example, dis‐
36       abling of PID caching can  be  configured  if  the  application  cannot
37       detect when a call to fork() has occurred.

EXAMPLE

40          #include <bson/bson.h>
41
42          int
43          main (int argc, char *argv[])
44          {
45             bson_context_t *ctx = NULL;
46             bson_oid_t oid;
47
48             /* use default context, via bson_context_get_default() */
49             bson_oid_init (&oid, NULL);
50
51             /* specify a local context for additional control */
52             ctx = bson_context_new (BSON_CONTEXT_DISABLE_PID_CACHE |
53                                     BSON_CONTEXT_THREAD_SAFE);
54             bson_oid_init (&oid, ctx);
55
56             bson_context_destroy (ctx);
57
58             return 0;
59          }
