Subdirectory Reference in C

I know this is not exactly what you are looking for but:

//Change the current working directory.

int _chdir( const char *dirname );
int _wchdir( const wchar_t *dirname );

//Searches for a file using environment paths.

void _searchenv( const char *filename, const char *varname, char *pathname );
void _wsearchenv( const wchar_t *filename, const wchar_t *varname, wchar_t *pathname );

//Changes the current working drive.

int _chdrive( int drive );

...maybe these will help. C often lacks the all-encompassing functions available to us in C++, but when used in cunjunction with each other these functions can acheive the results you desire.

C has no standard functions for this. Any functions to do this would be compiler and/or operating system specific.

C''s standard library doesn''t know about directories (nor does C++''s), you have to use something higher level. POSIX and the Win32 API (among other things) provide their own directory handling functions (POSIX: opendir, readdir, closedir, et cetera; Win32: FindFirstFile, FindNextFile, et cetera). Certain C runtimes (MSVC''s) provide some functions that wrap the platform that they run on''s functions (findfirstfile and findnextfile, if I recall correctly).

Boost provides some C++ directory handling wrappers. For C, you should probably wrap the platform specific functions yourself unless you happen to already be using a higher level library that provides the same thing.

To add a little follow up to Null And Void''s comments, although many of the functions that he mentions appear to be file oriented, they also return information about subdirectories. Review their documentation with an eye towards that.
