Open library file descriptors with O_CLOEXEC
|
|
This patch is non-portable, it needs linux 2.6.23 and glibc 2.7
|
|
or later, different combinations (old linux, new glibc and vice-versa)
|
|
will result in a crash.
|
|
|
|
To make it portable you have to test O_CLOEXEC support at *runtime*
|
|
compile time is not enough.
