BSON_ITER_BINARY(3) | libbson | BSON_ITER_BINARY(3) |
NAME¶
bson_iter_binary - bson_iter_binary()
SYNOPSIS¶
#define BSON_ITER_HOLDS_BINARY(iter) \
(bson_iter_type ((iter)) == BSON_TYPE_BINARY) void bson_iter_binary (const bson_iter_t *iter,
bson_subtype_t *subtype,
uint32_t *binary_len,
const uint8_t **binary);
PARAMETERS¶
- iter: A bson_iter_t.
- subtype: A location for a bson_subtype_t or NULL.
- binary_len: A location for the length of binary.
- binary: A location for a pointer to the immutable buffer.
DESCRIPTION¶
This function shall return the binary data of a BSON_TYPE_BINARY element. It is a programming error to call this function on a field that is not of type BSON_TYPE_BINARY. You can check this with the BSON_ITER_HOLDS_BINARY() macro or bson_iter_type().
The buffer that binary points to is only valid until the iterator's bson_t is modified or freed.
