Alright, this is what I got working for the posix stuff:
{.passL: "-lutil".}
var SIGWINCH* {.importc, header: "<signal.h>".}: cint
var TIOCGWINSZ* {.importc, header: "<termios.h>".}: cuint
var TIOCSWINSZ* {.importc, header: "<termios.h>".}: cuint
proc openpty (amaster, aslave : ptr int, mustBeNil : pointer, termp, winp :
ptr Termios) : cint {.importc, noDecl, header: "<pty.h>".}
proc forkpty (amaster: ptr int, mustBeNil : pointer, termp, winp : ptr
Termios) : cint {.importc, noDecl, header: "<pty.h>".}
I need to the put what will make **{.passL: "-lutil".}** happen in the importc
pragmas for openpty and forkpty, but I'm not sure how to do that. dynlib did
not do it.
With the above I was able to port the remaining C functions to Nim.
As far as **SigVal** not having **sival_int** an only having **sival_ptr**,
here was my workaround:
# for inserting:
var si_value:SigVal
si_value.sival_ptr = cast[pointer](myvar)
let rc = pid.sigqueue (SIGUSR2, si_value)
# for extracting:
proc handler (signal:cint, si: var SigInfo, context:pointer) {.noconv.} =
let myvar = cast[mytype](si.si_value.sival_ptr)
Where **mytype** objects are pointer sized or smaller, in my case I'm using an
enum type. I guess because of that, I don't really see the need to support
sival_int directly in Nim.
Should something like this be included in the PR?
Here is what is says currently:
SigVal* {.importc: "union sigval",
header: "<signal.h>", final, pure.} = object ## struct sigval
sival_ptr*: pointer ## pointer signal value;
## integer signal value not defined!
On a different note, why were these renamed?
* **cfmakeraw** to _cfMakeRaw_
* **tcsetattr** to _tcSetAttr_
* **tcgetattr** to _tcGetAttr_
Due to case insensitivity they worked without the camelcase. The reason I
initially thought they were missing was I could not find the in the
documentation.
readlink was not renamed to readLink, setgid to setGid, etc, so I don't really
see a point in renaming the aforementioned.
So, when I do a PR, I'll need to add the proper docstrings, for the new ones
above as well.
