文件句柄(File Handle)是操作系统中用于访问文件的一种数据结构,通常是一个整数或指针。文件句柄用于标识打开的文件,每个打开的文件都有一个唯一的文件句柄。 在Linux和Unix系统中,文件句柄是通过调用open()系统调用打开文件时返回的。当打开一个文件时,操作系统会为该文件分配一个文件句柄,并将其返回给应用程序。应...
pre>这个项目是其他人做的,他在python里面使用了一个包名叫“ploygons”,这个包好像是处理图像时比pandas还是什么快很多,但是这个包需要rust环境 cargo ,才能正常运行,在开发环境里安装rust环境还是比较轻松的。但是我现在需要测试放在docker环境运行,然后打包发送给别人。 https://segmentfault.com/q/1010000044893127...

Unlikefread,readrequires a file descriptor to indicate the file to read from. File descriptors are special integers linked to open file streams the program might have during execution. You can obtain a file descriptor using theopenfunction, storing it as anint. The otherreadarguments are the buf...
in rust with drop the value already stored at the pointer. In our case, this meant dropping totally random uninitialized bytes as if they were a tcp stream. By using std::ptr::write we avoid the drop. Otherwise, this PR just introduces auto free to tcp streams. 🎉 1 ️ 1 b...
The print() function in Python allows for the output of data to various streams, including files, by specifying the file parameter. This parameter directs the function’s output to the specified file object.The syntax for using the print() function with the file parameter to write to a ...

Your IBM code could then check the stdout and stderr streams and determine whether or not to invoke the conversion script.I'm also wondering whether it would make any difference if your IBM REXEC initiated the FTP command on the VAX itself.Regards,Ian 0 Kudos Reply Alex Tough Occasional...
