c - Doxygen group module from file -

is possible use doxygen grouping contents of given file grouped together, in doxygen calls "module"? including c library , in documentation want separate out library without having go through , manually document every item in library group member.

i found when using /// style documentation, adding

/// \addtogroup /// \{ 

at start of file, , adding

/// \} 

at end of file works purposes.
