JS_GetStringEncodingLength 编辑

This article covers features introduced in SpiderMonkey 1.8.5

Get the length of a JavaScript string in bytes.

Syntax

size_t
JS_GetStringEncodingLength(JSContext *cx, JSString *str);

Description

JS_GetStringEncodingLength returns the length of the specified string in bytes, regardless of its encoding. You can use this value to create a buffer to encode the string into using the JS_EncodeStringToBuffer function.

To encode to UTF8, use JS::GetDeflatedUTF8StringLength and JS::DeflateStringToUTF8Buffer instead.
