  73. .SH DESCRIPTION
  74. .IX Header "DESCRIPTION"
  75. \&\fBSSL_rstate_string()\fR returns a 2 letter string indicating the current read state
  76. of the SSL object \fBssl\fR.
  77. .PP
  78. \&\fBSSL_rstate_string_long()\fR returns a string indicating the current read state of
  79. the SSL object \fBssl\fR.
  80. .SH NOTES
  81. .IX Header "NOTES"
  82. When performing a read operation, the SSL/TLS engine must parse the record,
  83. consisting of header and body. When working in a blocking environment,
  84. SSL_rstate_string[_long]() should always return "RD"/"read done".
  85. .PP
  86. This function should only seldom be needed in applications.
  87. .SH "RETURN VALUES"
  88. .IX Header "RETURN VALUES"
  89. \&\fBSSL_rstate_string()\fR and \fBSSL_rstate_string_long()\fR can return the following
  90. values:
  91. .IP """RH""/""read header""" 4
  92. .IX Item """RH""/""read header"""
  93. The header of the record is being evaluated.
  94. .IP """RB""/""read body""" 4
  95. .IX Item """RB""/""read body"""
  96. The body of the record is being evaluated.
  97. .IP """unknown""/""unknown""" 4
  98. .IX Item """unknown""/""unknown"""
  99. The read state is unknown. This should never happen.
  100. .PP
  101. When used with QUIC SSL objects, these functions always return "RH"/"read
  102. header" in normal conditions.
