gettid: získat identifikaci vlákna

Originální popis anglicky: gettid - get thread identification

Návod, kniha: Linux Programmer's Manual

STRUČNĚ

#include <sys/types.h> #include <linux/unistd.h> _syscall0(pid_t,gettid) pid_t gettid(void);

POPIS / INSTRUKCE

gettid returns the thread ID of the current process. This is equal to the process ID (as returned by getpid(2)), unless the process is part of a thread group (created by specifying the CLONE_THREAD flag to the clone(2) system call). All processes in the same thread group have the same PID, but each one has a unique TID.

NÁVRATOVÁ HODNOTA

On success, returns the thread ID of the current process.

CHYBY / ERRORY

This call is always successful.

ODPOVÍDAJÍCÍ

gettid is Linux specific and should not be used in programs that are intended to be portable.
