The reason this is not working is that your main function doesn't have an event loop and/or doesn't block on the created thread.
An easy way out is to return the created thread tid, do not detach, and call pthread_join in main.
HTH.

pthread_attr_getdetachstate
PTHREAD_ATTR_SETDETACHSTATE(3) Linux Programmer's Manual PTHREAD_ATTR_SETDETACHSTATE(3)
NAME
pthread_attr_setdetachstate, pthread_attr_getdetachstate - set/get detach state attribute in thread attributes object
SYNOPSIS
#include <pthread.h>
int pthread_attr_setdetachstate(pthread_attr_t *attr, int detachstate);
int pthread_attr_getdetachstate(pthread_attr_t *attr, int *detachstate);
Compile and link with -pthread.
DESCRIPTION
The pthread_attr_setdetachstate() function sets the detach state attribute of the thread attributes object referred to by attr to the value
specified in detachstate. The detach state attribute determines whether a thread created using the thread attributes object attr will be
created in a joinable or a detached state.
The following values may be specified in detachstate:
PTHREAD_CREATE_DETACHED
Threads that are created using attr will be created in a detached state.
PTHREAD_CREATE_JOINABLE
Threads that are created using attr will be created in a joinable state.
The default setting of the detach state attribute in a newly initialized thread attributes object is PTHREAD_CREATE_JOINABLE.
The pthread_attr_getdetachstate() returns the detach state attribute of the thread attributes object attr in the buffer pointed to by
detachstate.
RETURN VALUE
On success, these functions return 0; on error, they return a nonzero error number.
ERRORS
pthread_attr_setdetachstate(3) can fail with the following error:
EINVAL An invalid value was specified in detachstate.
CONFORMING TO
POSIX.1-2001.
NOTES
See pthread_create(3) for more details on detached and joinable threads.
A thread that is created in a joinable state should eventually either be joined using pthread_join(3) or detached using pthread_detach(3);
see pthread_create(3).
It is an error to specify the thread ID of a thread that was created in a detached state in a later call to pthread_detach(3) or
pthread_join(3).
EXAMPLE
See pthread_attr_init(3).
