need to delay deleting a message

[Frank Kotler]

Code: [Select]

;section text
mov rdi,struc
mov rsi,struc
   call nanosleep

You want the name of the structure, "mytime", not the macro "struc" here.

Thanks Frank,
This gave the following errors in 64-bit
during the compile:

May not actually work, but it assembles.

Code: [Select]

;section data
extern nanosleep

struc timespec
  tv_sec resd 1
  tv_nsec resd 1
endstruc

mytime istruc timespec
   at tv_sec, dd 5
   at tv_nsec, dd 0
iend

;section text
mov rdi,mytime
mov rsi,mytime
   call nanosleep

Best,
Frank

Thanks for responding  Frank,

I had to make this change to the struc to get it to work:
    tv_sec resd 5

struc timespec
  tv_sec resd 1??
  tv_nsec resd 1
endstruc

Since I don't know what I am doing, is this correct??

The process is to put an error message on the screen and let the user
have time to read it. Then I delete the message.

I don't know. My 32-bit man page says "time_t" for the seconds and "long" for nanoseconds. I tried to look up "time_t" and I still can't say I know...

I don't see any reason why we should reserve any more than 8 bytes, tops. Maybe you've got a really long error message, or a really slow-reading user. I'm an old geezer, and 2038 does not seem like a problem to me.

If one way works and the other doesn't, go with the way that works!

Best,
Frank
