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().
