  36 .Sh NAME
  37 .Nm pthread_detach
  38 .Nd detach a thread
  39 .Sh SYNOPSIS
  40 .Fd #include <pthread.h>
  41 .Ft int
  42 .Fn pthread_detach "pthread_t thread"
  43 .Sh DESCRIPTION
  44 The
  45 .Fn pthread_detach
  46 function is used to indicate to the implementation that storage for the
  47 thread
  48 .Fa thread
  49 can be reclaimed when the thread terminates.
  50 If
  51 .Fa thread
  52 has not terminated,
  53 .Fn pthread_detach
  54 will not cause it to terminate.
  55 The effect of multiple
  56 .Fn pthread_detach
  57 calls on the same target thread is unspecified.
  58 .Sh RETURN VALUES
  59 If successful,  the
  60 .Fn pthread_detach
  61 function will return zero.
  62 Otherwise an error number will be returned to
  63 indicate the error.
  64 Note that the function does not change the value
  65 of errno as it did for some drafts of the standard.
  66 These early drafts
  67 also passed a pointer to pthread_t as the argument.
  68 Beware!
  69 .Sh ERRORS
  70 .Fn pthread_detach
  71 will fail if:
  72 .Bl -tag -width Er
  73 .It Bq Er EINVAL
  74 The implementation has detected that the value specified by
  75 .Fa thread
  76 does not refer to a joinable thread.
  77 .It Bq Er ESRCH
  78 No thread could be found corresponding to that specified by the given
  79 thread ID,
  80 .Fa thread .
