BSON_APPEND_VECTOR_PACKED_BIT_FROM_ARRAY(3)

SYNOPSIS

    #define BSON_APPEND_VECTOR_PACKED_BIT_FROM_ARRAY(b, key, iter, err) \
       bson_append_vector_packed_bit_from_array (b, key, (int) strlen (key), iter, err)
    bool
    bson_append_vector_packed_bit_from_array (bson_t *bson,
                                              const char *key,
                                              int key_length,
                                              const bson_iter_t *iter,
                                              bson_error_t *error);

PARAMETERS

•   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().

•   iter: A bson_iter_t referencing array elements that will be converted.

•   error: Optional bson_error_t for detail about conversion failures.

DESCRIPTION

Appends a new field to bson by converting an Array to a Vector of packed_bit elements.

For the conversion to succeed, every item in the Array must be either an integer (BSON_TYPE_INT32 or BSON_TYPE_INT64) with the values 0 or 1, or boolean (BSON_TYPE_BOOL). If any element has an incorrect type or an out-of-range value, the conversion fails with an error message providing details, and no changes are made to bson.

The provided iter must be positioned just prior to the first element of the BSON Array. If your input is a bare BSON Array, set up iter using bson_iter_init(). If the input is within a document field, use bson_iter_recurse().

RETURNS

Returns true if the operation was applied successfully. On error, returns false and writes additional error information to error without modifying bson. The error will have a domain of BSON_ERROR_VECTOR and a code from bson_vector_error_code_t.
