  73. .SH DESCRIPTION
  74. .IX Header "DESCRIPTION"
  75. \&\fBDTLSv1_handle_timeout()\fR handles any timeout events which have become pending
  76. on a DTLS or QUIC SSL object.
  77. .PP
  78. Use \fBDTLSv1_get_timeout\fR\|(3) or \fBSSL_get_event_timeout\fR\|(3) to determine
  79. when to call \fBDTLSv1_handle_timeout()\fR.
  80. .PP
  81. This function is only applicable to DTLS or QUIC SSL objects. It returns 0 if
  82. called on any other kind of SSL object.
  83. .PP
  84. \&\fBSSL_handle_events\fR\|(3) supersedes all use cases for this function and may
  85. be used instead of it.
  86. .SH "RETURN VALUES"
  87. .IX Header "RETURN VALUES"
  88. Returns 1 if there was a pending timeout event and it was handled successfully.
  89. .PP
  90. Returns 0 if there was no pending timeout event, or if the SSL object is not a
  91. DTLS or QUIC object.
  92. .PP
  93. Returns \-1 if there was a pending timeout event but it could not be handled
  94. successfully.
  95. .SH "SEE ALSO"
