4.线程的取消/清理/互斥锁
不会编程喵的博客
10-14 688
在Linux中，互斥锁并不占用任何资源，因此LinuxThreads中的 pthread_mutex_destroy()除了检查锁状态以外（锁定状态则返回EBUSY）没有其他动作。写者：写者使用写锁，如果当前没有读者，也没有其他写者，写者立即获得写锁；否则写者将等待，直到没有读者和写者。读写锁出于写锁状态时，所有试图对读写锁加锁的线程，不管是读者试图加读锁，还是写者试图加写锁，都会被阻塞。读写锁处于读锁状态时，有写者试图加写锁时，之后的其他线程的读锁请求会被阻塞，以避免写者长时间的不写锁。

man pthread_cond_xxx 一系列的函数都天汇 Nomanual; 解决办法： 1. # apt-get installmanages-posixmanages-posix-dev 2. #apt install glibc-doc --------------------- 说明：manpages-posix-dev包含 POSIX 的 header files 和 library calls 的用法，而pthread_cond_init并不属于Linux命令，而是属于C/...

在查看线程部分的MAN手册时，提示No manual entry for pthread_create in section 3 解决办法： sudo apt-get install manpages-posix manpages-posix-dev 之后在进行MAN命令查看手册就可以了

looking for pthread_create - not found
09-07
根据提供的信息，"looking for pthread_create - not found" 是一个错误信息，通常在编译和链接过程中出现。这个错误信息表示编译器在链接时找不到 pthread_create 函数。pthread_create 是 POSIX 线程库中的函数，用于创建一个新的线程。 要解决这个错误，我们需要确保以下几点： 1. 确保编译器已经正确地安装和配置。POSIX 线程库通常是标准的 C 库的一部分，但某些系统可能需要额外的安装步骤。请确保编译器的安装和配置是正确的。 2. 确保在编译时链接了 pthread 库。在编译时，需要指定 -pthread 或 -lpthread 选项，这样编译器才能找到并链接上正确的线程库。请确保在编译命令中包含这些选项。 例如，在编译一个名为 program.c 的源文件时，你可以使用以下命令： ``` gcc -o program program.c -pthread ``` 3. 确保源代码中包含正确的头文件。在使用 pthread_create 函数之前，需要包含 pthread.h 头文件。请确保源代码中包含了此头文件。 以上是可能导致 "looking for pthread_create - not found" 错误的常见原因和解决方法。如果问题仍然存在，请检查编译器和库的版本兼容性，并确保代码中正确地使用了 pthread_create 函数。
