Description

JS_CompileUCScript compiles a script using a Unicode character set, chars, for execution. The script is associated with a JS object. chars is the Unicode string containing the text of the script. length indicates the size of the script in characters.

filename is the name of the file (or URL) containing the script. This information in included in error messages if an error occurs during compilation. Similarly, lineno is used to report the line number of the script or file where an error occurred during compilation.

If a script compiles successfully, JS_CompileUCScript returns a pointer to the compiled script. Otherwise JS_UCCompileScript returns NULL, and reports an error.

Notes

To compile a script from an external file source rather than passing the actual script as an argument, use JS_CompileFile instead of JS_CompileScript.
