Macro Definition Documentation

◆ FPS

#define FPS   (75)
  • On sector contains 75 frames per CD specs

Definition at line 39 of file cuesheetparser.cc.

◆ VAL_OR_EMPTY

#define VAL_OR_EMPTY (   val)    ((val) != nullptr ? (val) : "")
  • Return string or empty string if val is nullptr

Definition at line 40 of file cuesheetparser.cc.

Function Documentation

◆ check_cuesheet()

int check_cuesheet ( const std::string &  filename,
void *  buf = nullptr,
fuse_fill_dir_t  filler = nullptr 
)

Get number of titles in cue sheet.

Parameters
[in]filename- Path to check
[in,out]buf- The buffer passed to the readdir() operation.
[in,out]filler- Function to add an entry in a readdir() operation (see https://libfuse.github.io/doxygen/fuse_8h.html#a7dd132de66a5cc2add2a4eff5d435660)
Note
buf and filler can be nullptr. In that case the call will run faster, so these parameters should only be passed if to be filled in.
Returns
-errno or number or titles in cue sheet
