bson_context_t - bson_context_t

BSON OID Generation Context

#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_GNUC_CONST; bson_context_t * bson_context_new (bson_context_flags_t flags); void bson_context_destroy (bson_context_t *context);


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.

#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; }
