pthread_equal - compare thread IDs
#include <pthread.h> int pthread_equal(pthread_t t1, pthread_t t2); Compile and link with -pthread.
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.1-2001, POSIX.1-2008.
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.
