Function Documentation

char* jspf_error

(

)

Return a descriptive message for the error occured in the last call to jspf_*.

The memory returned is allocated statically, it must not be free'd. This function may only be used directly after an error occured(!), calling another jspf_* function after the failing call and jspf_error() is undefined behaviour.

Returns

Pointer the message

Here is the caller graph for this function:

static void jspf_filewriter ( void *  ctx, const char *  str, size_t  len  )

static

YAJL print callback function for writing JSPF.

Parameters

ctx	A context, here: a FILE* receiving the JSPF
str	The string to write to file
len	The length of str

Here is the caller graph for this function:

struct track_list* jspf_read

(

char *

file

)

Read a JSPF playlist to a track_list.

Parameters

file	The file to read from

Returns

The track_list containing data from file (or an empty list in case of error)
