c++ - boost deadline_timer - max number of timers in Linux

Question

Does anyone know what the max number of simultaneous boost deadline_timer instances can be created within a process in Linux? I believe boost uses the Posix timer_create method.

Answer 1

从 Linux timer_create 手册页：

The kernel preallocates a "queued real-time signal" for each timer created
using timer_create().  Consequently, the number of timers is limited by the
RLIMIT_SIGPENDING resource limit (see setrlimit(2)).

在 bash 中使用ulimit -i来获取或设置 RLIMIT_SIGPENDING。在我的 Ubuntu 服务器上，该限制默认为 16382。
