YAJL_API yajl_handle yajl_alloc ( const yajl_callbacks callbacks,
const yajl_parser_config config,
const yajl_alloc_funcs allocFuncs,
void *  ctx 
)

allocate a parser handle

Parameters:
callbacksa yajl callbacks structure specifying the functions to call when different JSON entities are encountered in the input text. May be NULL, which is only useful for validation.
configconfiguration parameters for the parse.
ctxa context pointer that will be passed to callbacks.
