Greetings,

Coming across a list of undocumented extended stored procedures I wonder, where the actual T-SQL code of them can be looked up?

Here is the xp list:
sp_MSgetversion
xp_dirtree
xp_enum_oledb_providers
xp_enumcodepages
xp_enumdsn
xp_enumerrorlogs
xp_enumgroups
xp_fileexist
xp_fixeddrives
xp_getnetname
xp_readerrorlog
xp_regdeletekey
xp_regdeletevalue
xp_regread
xp_regwrite
xp_subdirs

More info about them can be found at [url]http://www.mssqlcity.com/Articles/Undoc/UndocExtSP.htm[/url]

Extended procedures are not written in T-SQL. They are typically written in C++. The compiled DLLs are registered for use so the source code is not available (especially Microsoft, especially for undocumented code)
