|
|
3216 | If defined to be C<1>, libev will try to use a direct syscall instead |
|
|
3217 | of calling the system-provided C<clock_gettime> function. This option |
|
|
3218 | exists because on GNU/Linux, C<clock_gettime> is in C<librt>, but C<librt> |
|
|
3219 | unconditionally pulls in C<libpthread>, slowing down single-threaded |
|
|
3220 | programs needlessly. Using a direct syscall is slightly slower, because |
|
|
3221 | no optimised vdso implementation can be used, but avoids the pthread |
|
|
3222 | dependency. Defaults to C<1> on GNU/Linux with glibc 2.x or higher. |
