bson_append_symbol − bson_append_symbol()
#define BSON_APPEND_SYMBOL(b, key, val) \ bson_append_symbol (b, key, (int) strlen (key), val, (int) strlen (val)) bool bson_append_symbol (bson_t *bson, const char *key, int key_length, const char *value, int length);
• |
bson: A bson_t. | ||
• |
key: An ASCII C string containing the name of the field. | ||
• |
key_length: The length of key in bytes, or −1 to determine the length with strlen(). | ||
• |
value: The symbol. | ||
• |
length: A length of symbol in bytes, or −1 to determine the length with strlen(). |
Appends a new field to bson of type BSON_TYPE_SYMBOL. This BSON type is deprecated and should not be used in new code.
Due to legacy behavior, passing NULL for value appends a null value, not a symbol value. To append a null value directly, prefer using bson_append_null().
Returns true if the operation was applied successfully. The function will fail if appending the value grows bson larger than INT32_MAX.
