Function Documentation

spa_json_init()

static void spa_json_init ( struct spa_json * iter, const char * data, size_t size )

inlinestatic

spa_json_enter()

spa_json_next()

static int spa_json_next ( struct spa_json * iter, const char ** value )

inlinestatic

Get the next token.

value points to the token and the return value is the length. Returns -1 on parse error, 0 on end of input.

spa_json_get_error()

static bool spa_json_get_error ( struct spa_json * iter, const char * start, struct spa_error_location * loc )
