SYNOPSIS

          #define BSON_APPEND_VECTOR_FLOAT32_FROM_ARRAY(b, key, iter, err) \
             bson_append_vector_float32_from_array (b, key, (int) strlen (key), iter, err)

          bool
          bson_append_vector_float32_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 float32 elements.

       For  the  conversion  to succeed, every item in the Array must be double-precision floating point number.
       (BSON_TYPE_DOUBLE)

       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 <>.
