Functions

func Free added in v0.9.3 

func Free(ptr unsafe.Pointer)

CJSON_PUBLIC(void) cJSON_free(void *object);

func FreeCStr added in v0.9.3 

func FreeCStr(*c.Char)

func GetErrorPtr() *c.Char

CJSON_PUBLIC(const char *) cJSON_GetErrorPtr(void);

For analysing failed parses. This returns a pointer to the parse error. You'll probably need to look a few chars back to make sense of it. Defined when cJSON_Parse() returns 0. 0 when cJSON_Parse() succeeds.

Minify a strings, remove blank characters(such as ' ', '\t', '\r', '\n') from strings. The input pointer json cannot point to a read-only address area, such as a string constant, but should point to a readable and writable address area.
