-.Sh LIBRARY
-.Lb libc_r
-.Sh SYNOPSIS
-.In pthread.h
-.Ft int
-.Fn pthread_setspecific "pthread_key_t key" "const void *value"
-.Sh DESCRIPTION
-The
-.Fn pthread_setspecific
-function associates a thread-specific value with a
-.Fa key
-obtained via a previous call to
-.Fn pthread_key_create .
-Different threads man bind different values to the same key.
-These values are
-typically pointers to blocks of dynamically allocated memory that have been
-reserved for use by the calling thread.
-.Pp
-The effect of calling
-.Fn pthread_setspecific
-with a key value not obtained from
-.Fn pthread_key_create
-or after
-.Fa key
-has been deleted with
-.Fn pthread_key_delete
-is undefined.
-.Pp
-The
-.Fn pthread_setspecific
-function may be called from a thread-specific data destructor function,
-however this may result in lost storage or infinite loops.
-.Sh RETURN VALUES
-If successful, the
-.Fn pthread_setspecific
-function will return zero.
-Otherwise an error number will be returned to
-indicate the error.
-.Sh ERRORS
-The
-.Fn pthread_setspecific
-function will fail if:
-.Bl -tag -width Er
-.It Bq Er ENOMEM
-Insufficient memory exists to associate the value with the
-.Fa key .
-.It Bq Er EINVAL
-The
-.Fa key
-value is invalid.

-.Sh SEE ALSO
-.Xr pthread_getspecific 3 ,
-.Xr pthread_key_create 3 ,
