When reading this kind of file, my writing speed is not good,

How can I read faster? ?

Help me see the code,

Post the structure of shi

onethen123

shi is int

Do not care. .
Just write one for me in tc

onethen123

I am comparing the first field if it is equal, I will save the last few fields into the global array and then process. .

But my query is very slow, can you help me write it well? .

Check it out soon? ?

yoh2006

Can't see where it affects the speed
but
filename[strlen(filename)]=0x0;
Read_CopyFile[i][g].name5[strlen(Read_CopyFile[i][g].name5)]=0x0;
Such statements should be deleteable

onethen123

Is there any other way to hurry up?
It's too slow

If you can use multithreading, it would be great,
You can build a watch and read it while looking for it, which is very convenient
Or read it into the memory all at once, and then search.

onethen123

Hey. . . . . . . . . . . . . . . . .
I'm so depressed.
Is there no good way to use c language? I can't use c.
