Incremental read function needs `char*` but docs say `const char*` as first arg

[rath3t]

Describe the bug
I'm currently trying to use the new incremental read feature from #199 .
The docs say that

const char *dat = your_file.bytes;
//...
 
yyjson_incr_state  *state = yyjson_incr_new(dat, len, flg, NULL);

gives for me a compile time error since yyjson_incr_new expects a mutable char *.

Your environment

• Compiler: clang++ 18

Additional context
The test use always a mutable pointer.

Can the first argument be a const char pointer or does only the documentation has to be changed?

The incremental read feature came from #199.

If you're not using YYJSON_READ_INSITU, you can just cast const char* to char*, just like this:

yyjson/src/yyjson.h

Lines 940 to 946 in 484aefb

	yyjson_api_inline yyjson_doc *yyjson_read(const char *dat,
	size_t len,
	yyjson_read_flag flg) {
	flg &= ~YYJSON_READ_INSITU; /* const string cannot be modified */
	return yyjson_read_opts((char *)(void *)(size_t)(const void *)dat,
	len, flg, NULL, NULL);
	}

I'll tweak the docs to make this clearer soon.

Hei,
yes casting is what I'm doing currently. Thanks!
