BSON_ITER_UTF8(3) libbson BSON_ITER_UTF8(3) SYNOPSIS #define BSON_ITER_HOLDS_UTF8(iter) (bson_iter_type ((iter)) == BSON_TYPE_UTF8) const char * bson_iter_utf8 (const bson_iter_t *iter, uint32_t *length); PARAMETERS * iter: A bson_iter_t. * length: An optional location for the length of the resulting UTF-8 en- coded string. DESCRIPTION The bson_iter_utf8() function shall retrieve the contents of a BSON_TYPE_UTF8 element currently observed by iter. It is invalid to call this function while observing an element other than BSON_TYPE_UTF8. RETURNS A UTF-8 encoded string that has not been modified or freed. It is suggested that the caller validate the content is valid UTF-8 before using this in other places. That can be done by calling bson_utf8_validate() or validating the underlying bson_t before iterating it. Note that not all drivers use multi-byte representation for \0 in UTF-8 en- codings (commonly referred to as modified-UTF8). You probably want to take a look at the length field when marshaling to other runtimes. AUTHOR MongoDB, Inc COPYRIGHT 2009-present, MongoDB, Inc. 1.30.8 Aug 27, 2026 BSON_ITER_UTF8(3)
