POSIX specification:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/posix_spawn.html
Gnulib module: posix_spawn
Portability problems fixed by Gnulib:
- This function is missing on some platforms:
FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.3, AIX 5.1, HP-UX 11, Solaris 9, Cygwin 1.7.x, mingw, MSVC 14, Android 8.1.
- When this function fails, it causes the stdio buffer contents to be output
twice on some platforms:
AIX 6.1.
- When the program to be invoked is an executable script without a ‘#!’
marker in the first line, this function executes the script as if it were
a shell script, on some platforms:
GNU/Hurd.
Portability problems not fixed by Gnulib:
- This function does not work on some platforms:
AIX 6.1 (under particular circumstances).
The Gnulib modules posix_spawn_file_actions_addchdir and
posix_spawn_file_actions_addfchdir provide additional actions,
that consist in changing the current directory of the child process
before starting the specified program.
