54 functions set the internal name of the thread specified by the
56 argument to the string value specified by the
61 .Fn pthread_get_name_np
63 .Fn pthread_getname_np
64 functions get the internal name of the thread specified by the
66 argument and store it in the buffer.
67 If the thread does not exist, the buffer is written as an empty line.
69 Upon successful completion,
70 .Fn pthread_getname_np

74 Otherwise, an error is returned.
77 .Fn pthread_getname_np

80 functions will fail if
85 parameter is outside the process's allocated address space.
89 argument specifies an invalid thread.
91 No thread could be found in the current process corresponding to that
92 specified by the given thread ID
96 Because of the debugging nature of the
97 .Nm pthread_get_name_np
99 .Nm pthread_set_name_np
100 functions, all errors that may appear inside are silently ignored.
101 However, errno may still be set.
106 .Fn pthread_set_name_np
108 .Fn pthread_get_name_np
109 functions are non-standard extensions.
110 While also non-standard,
111 .Fn pthread_setname_np
113 .Fn pthread_getname_np
114 are implemented by a larger number of operating
115 systems so they are in fact more portable.
