epoll_create1 - create a new instance of an epoll set for monitoring file descriptors
The epoll_create1() system call performs the same task as epoll_create(), but it allows for additional features that are beneficial for certain applications. Flags specifies the behavior of the system call and may be used to specify a maximum number of descriptors that the target epoll instance will be able to contain (flags is a bitmask, and only one of the flags in the mask should be used). This syscall is useful in applications that depend on high performance and scalability, such as network servers.
int[OPT] - bits that specify the behavior of the system call. The flags may be a bitmask specifying the behavior of the system call. The only flag that should be used is EPOLL_CLOEXEC, which creates the epoll instance with the close-on-exec flag.
- K - Originated from kernel-space.
- U - Originated from user space (for example, pointer to user space memory used to get it)
- TOCTOU - Vulnerable to TOCTOU (time of check, time of use)
- OPT - Optional argument - might not always be available (passed with null value)
To monitor the execution of the epoll_create1 system call.
Example Use Case¶
The epoll_create1 system call can be used to create a new instance of an epoll set for monitoring a large number of file descriptors. This system call is particularly useful for servers that constantly need to monitor a large number of file descriptors.
- epoll_ctl - used to control an instance of an epoll set
- epoll_wait - used to wait for events from an instance of an epoll set
