bool nav_flat_fileisnotopen ( void  )

This function checks if no file is opened.

Returns
true if no file is opened
false if a file is opened

bool nav_flat_findname ( const FS_STRING  sz_name,
bool  b_match_case 
)

This function searches a file name in file list FLAT.

@param     sz_name        name to search (UNICODE or ASCII) <br>
                          It must be terminated by NULL or '*' value
@param     b_match_case   false to ignore the case

@return    false in case of error, see global value "fs_g_status" for more detail
@return    true otherwise
//! This function starts a search at the next position of the current in file list
//!
