then use the FD value as the index to find the corresponding structure, the structure is the following ANFD structure (omitted on the Windows system variables). This method can be indexed in O (1) complexity, and the question is how much space it occupies. If we open 1 million fd at the same time, the space occupied is 10^6*sizeof (ANFD), about 12M, this is completely acceptable. The meaning of the fields in the struct is gradually mentioned later in the introduction of the Libev process.
