How to install
on macOS (Homebrew)
brew install cjson
on Linux (Debian/Ubuntu)
apt-get install -y libcjson-dev
Demos
The _demo directory contains our demos (it start with _ to prevent the go command from compiling it):
- mkjson: create a json object and print it
How to run demos
To run the demos in directory _demo:
cd <demo-directory> # eg. cd _demo/mkjson

Functions ¶
func FreeCStr ¶
malloc/free objects using the malloc/free functions that have been set with cJSON_InitHooks
func GetErrorPtr ¶
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.
func Malloc ¶

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.

Create an object that only references it's elements so they will not be freed by Delete
func Parse ¶
CJSON_PUBLIC(cJSON *) cJSON_Parse(const char *value);
Memory Management: the caller is always responsible to free the results from all variants of cJSON_Parse (with cJSON_Delete) and cJSON_Print (with stdlib free, cJSON_Hooks.free_fn, or cJSON_free as appropriate). The exception is cJSON_PrintPreallocated, where the caller has full responsibility of the buffer.
func ParseBytes ¶
func ParseString ¶
func ParseWithLength ¶
CJSON_PUBLIC(cJSON *) cJSON_ParseWithLength(const char *value, size_t buffer_length);
Memory Management: the caller is always responsible to free the results from all variants of cJSON_Parse (with cJSON_Delete) and cJSON_Print (with stdlib free, cJSON_Hooks.free_fn, or cJSON_free as appropriate). The exception is cJSON_PrintPreallocated, where the caller has full responsibility of the buffer.
