You give each thread a name with this (non-portable) pthread api: This name is visible in thread-level "ps" output (so "ps -L PID"). I recommend to give every thread a human-readable name. The thread ID returned by this call is not the same thing as a POSIX thread ID (i.e., the opaque value returned by pthread_self(3)). Glibc does not provide a wrapper for this system call call it using syscall(2). Note: There is no glibc wrapper for this system call see NOTES. Snprintf(fname, sizeof(fname), "/proc/self/task/%d/stat", (int) get_task_id())
As noted in the man page (see quotes), there is no direct API to gettid, instead the syscall is neededįor code that can be used inside an app, see below That leave with the task of mapping threads to TASKID.
