C : how can I change from file descriptor to FILE struct and vice versa?
提问by trrrrrrm
Is there any way to change an intfile descriptor to a FILEstruct pointer or/and change FILE*to a file descriptor in C?
有没有办法将int文件描述符更改为FILE结构指针或/和更改FILE*为 C 中的文件描述符？

The function fdopen()returns a new (FILE *) associated with an open file descriptor.
该函数fdopen()返回一个与打开的文件描述符相关联的新 (FILE *)。
The function fileno()returns the file descriptor associated with an open FILE *.
该函数fileno()返回与打开的 FILE * 关联的文件描述符。
