BSON_CONTEXT_T(3) libbson BSON_CONTEXT_T(3) 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_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_CON- TEXT_DISABLE_PID_CACHE are the only ones used. The others have no ef- fect. 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; } AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.2 Apr 12, 2025 BSON_CONTEXT_T(3)
