BSON_ITER_BINARY(3)

NAME
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(3) .
