pthread_equal(3) Library Functions Manual pthread_equal(3)
pthread_equal - compare thread IDs
POSIX threads library (libpthread, -lpthread)
#include <pthread.h> int pthread_equal(pthread_t t1, pthread_t t2);
The pthread_equal() function compares two thread identifiers.
If the two thread IDs are equal, pthread_equal() returns a nonzero value; otherwise, it returns 0.
This function always succeeds.
For an explanation of the terms used in this section, see attributes(7). ┌─────────────────────────────────────┬───────────────┬─────────┐ │ Interface │ Attribute │ Value │ ├─────────────────────────────────────┼───────────────┼─────────┤ │ pthread_equal() │ Thread safety │ MT-Safe │ └─────────────────────────────────────┴───────────────┴─────────┘
POSIX.1-2008.
POSIX.1-2001.
The pthread_equal() function is necessary because thread IDs should be considered opaque: there is no portable way for applications to directly compare two pthread_t values.
