This pull request adds LibTTY which provides access to ‘libtty’, the library added in Pharo VM pull request #742, offering a function to spawn a process connected to a pseudo-terminal. It also adds some methods on LibC which are needed for LibTTYTest, and factors out LibCTypes.
Note that LibCTypes, as well as
#flagOpenRDWR
and#getProcessStatus:
on LibTTYTest, make assumptions about the definitions ofssize_t
,pid_t
,O_RDWR
,WIFEXITED
,WEXITSTATUS
,WIFSIGNALED
andWTERMSIG
that are not guaranteed by POSIX.1-2017, but they work for Linux and macOS.
