NAME

bson_append_code_with_scope - bson_append_code_with_scope()

SYNOPSIS

#define BSON_APPEND_CODE_WITH_SCOPE(b, key, val, scope) \
   bson_append_code_with_scope (b, key, (int) strlen (key), val, scope)
bool
bson_append_code_with_scope (bson_t *bson,
                             const char *key,
                             int key_length,
                             const char *javascript,
                             const bson_t *scope);


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().
  • javascript: A NULL-terminated UTF-8 encoded string containing the javascript fragment.
  • scope: Optional bson_t containing the scope for javascript.

DESCRIPTION

The bson_append_code_with_scope() function shall perform like bson_append_code() except it allows providing a scope to the javascript function in the form of a bson document.

If scope is NULL, this function appends an element with BSON type "code", otherwise with BSON type "code with scope".

RETURNS

Returns true if the operation was applied successfully. The function will fail if appending javascript and scope grows bson larger than INT32_MAX.
