Question

我找不到在C

中将guint8转换为uint32_t的方法

我试过了：

'use strict';

var watchify = require('watchify');
var browserify = require('browserify');
var gulp = require('gulp');
var source = require('vinyl-source-stream');
var buffer = require('vinyl-buffer');
var gutil = require('gulp-util');
var sourcemaps = require('gulp-sourcemaps');
var assign = require('lodash.assign');

// add custom browserify options here
var customOpts = {
  entries: ['./function.js'],
  standalone: 'function',
};
var opts = assign({}, watchify.args, customOpts);
var b = watchify(browserify(opts)); 

// add transformations here
// i.e. b.transform(coffeeify);

gulp.task('js', bundle); // so you can run `gulp js` to build the file
b.on('update', bundle); // on any dep update, runs the bundler
b.on('log', gutil.log); // output build logs to terminal

function bundle() {
  return b.bundle()
    // log errors if they happen
    .on('error', gutil.log.bind(gutil, 'Browserify Error'))
    .pipe(source('bundle.js'))
    // optional, remove if you don't need to buffer file contents
    .pipe(buffer())
    // optional, remove if you dont want sourcemaps
    .pipe(sourcemaps.init({loadMaps: true})) // loads map from browserify file
       // Add transformation tasks to the pipeline here.
    .pipe(sourcemaps.write('./')) // writes .map file
    .pipe(gulp.dest('./dist'));
}

但它说：

uint32_t *uint32_value = (uint32_t *)guint8_value;

Answer 1

您不能从guint8投射到uint32_t。

您正在从整数（guint8）转换为指向整数的指针（uint32_t*）

正确的代码非常简单：

uint32_t uint32_value = guint8_value;

在C / glib中将guint8转换为uint32_t
