BSON_ITER_BINARY(3) Library Functions Manual BSON_ITER_BINARY(3)

NAME

bson_iter_binary() - 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().

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(3)

The buffer that binary points to is only valid until the iterator's bson_t is modified or freed.
