       bson_append_value()  - Appends a new field to bson by determining the boxed type in value. This is useful
       if you want to copy fields between documents but do not know the field type until runtime.

SYNOPSIS

       bool
       bson_append_value (bson_t             *bson,
                          const char         *key,
                          int                 key_length,
                          const bson_value_t *value);

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(3) \&.

       value  A bson_value_t \&.

DESCRIPTION

       Appends a new field to bson by determining the boxed type in value \&. This is useful if you want to copy
