Optionally specify `which` area of the stream buffer. The `seekpos` operation will fail if `which` does not include the flag `bsl::ios_base::out` or if `position` is less then zero or greater than `length()`. == Synopsis Declared in `<bdlsb_memoutstreambuf.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- virtual pos_type seekpos( pos_type position, std::ios_base::openmode which = bsl::ios_base::in | bsl::ios_base::out) override; ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
