Just learning about the privilege escalation method provided by setuid. Correct me if I am wrong but what it does is change the uid of the current process to whatever uid I set. Right ?

pthread_detach
PTHREAD_DETACH(3) BSD Library Functions Manual PTHREAD_DETACH(3)
NAME
pthread_detach -- detach a thread
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
SYNOPSIS
#include <pthread.h>
int
pthread_detach(pthread_t thread);
DESCRIPTION
The pthread_detach() function is used to indicate to the implementation that storage for the thread thread can be reclaimed when the thread
terminates. If thread has not terminated, pthread_detach() will not cause it to terminate. The effect of multiple pthread_detach() calls on
the same target thread is unspecified.
RETURN VALUES
If successful, the pthread_detach() function will return zero. Otherwise an error number will be returned to indicate the error. Note that
the function does not change the value of errno as it did for some drafts of the standard. These early drafts also passed a pointer to
pthread_t as the argument. Beware!
ERRORS
The pthread_detach() function will fail if:
[EINVAL] The implementation has detected that the value specified by thread does not refer to a joinable thread.
[ESRCH] No thread could be found corresponding to that specified by the given thread ID, thread.
SEE ALSO
pthread_join(3)
STANDARDS
The pthread_detach() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
