BSON_CONTEXT_T(3)

NAME
bson_context_t - bson_context_t

BSON OID Generation Context

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_GNUC_CONST;
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;
}
