pid_t 是那一种数据类型: 是Linux下的进程号类型,也就是Process ID _ Type 的缩写。 其实是宏定义的unsigned int类型, warning: format ‘%u’ expects type ‘unsigned int’, but argument 2 has type ‘pthread_t’: 使用%lu打印pthread_t不会出现警告。 二)线程ID: 编译时如果使用%x打印pthread_t会出...
针对你遇到的“error: unknown type name 'pthread_t'”错误,以下是一些可能的解决步骤: 确认'pthread_t'未定义的原因: 这个错误通常表明编译器在编译时未能识别pthread_t类型。pthread_t是POSIX线程库中定义的一个数据类型,用于表示线程标识符。 检查并包含正确的头文件: 要使用POSIX线程库中的功能,你需要包含...
pthread_t; /* Thread identifiers. The structure of the attribute type is not exposed on purpose. */ typedef unsigned long int pthread_t; 总结:可以看到pthread_t 就是unsigned long int ,在本系统中占用8个字节 ,即为uint64,打印线程ID需要用%lu格式。 第二: linux右上角键盘消失 如果用的是ibus: ...
在linux中可以使用pthread_t来查看对应变量的定义 #include <pthread.h> #include <unistd.h> pthread_t; /* Thread identifiers. The structure of the attribute type is not exposed on purpose. */ typedef unsigned long int pthread_t; 总结:可以看到pthread_t 就是unsigned long int ,在本系统中占用8...
pthread_t定义结构linux下被定义为:在linux履⾏pthread_t它被定义为 "unsigned long int",参考 Windows下这样定义:/* * Generic handle type - intended to extend uniqueness beyond * that available with a simple pointer. It should scale for either * IA-32 or IA-64.*/ typedef struct { void *...

`pthread_mutex_t`, `sem_t` in a `std::map`, The other thing is, instead of having two maps, you can have a map<subscription_type, object_struct>. struct object_struct { bool valid; …

1.mutex初始化。 var mutex = pthread_mutex_t() var attr: pthread_mutexattr_t = pthread_mutexattr_t() pthread_mutexattr_init(&attr) pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE) pthread_mutex_init(&mutex, &attr) 2.mutex使用。
