It was generated by gdoc. .TH "gnutls_record_get_direction" 3 "2.4.2" "gnutls" "gnutls" .SH NAME gnutls_record_get_direction \- return the direction of the last interrupted function call .SH SYNOPSIS .B #include <gnutls/gnutls.h> .sp .BI "int gnutls_record_get_direction(gnutls_session_t " session ");" .SH ARGUMENTS .IP "gnutls_session_t session" 12 is a \fBgnutls_session_t\fP structure. .SH "DESCRIPTION" This function provides information about the internals of the record protocol and is only useful if a prior gnutls function call (e.g. \fBgnutls_handshake()\fP) was interrupted for some reason, that is, if a function returned \fBGNUTLS_E_INTERRUPTED\fP or \fBGNUTLS_E_AGAIN\fP. In such a case, you might want to call \fBselect()\fP or \fBpoll()\fP before calling the interrupted gnutls function again. To tell you whether a file descriptor should be selected for either reading or writing, \fBgnutls_record_get_direction()\fP returns 0 if the interrupted function was trying to read data, and 1 if it was trying to write data. .SH "RETURNS" 0 if trying to read data, 1 if trying to write data. .SH "REPORTING BUGS" Report bugs to <bug-gnutls@gnu.org>. .SH COPYRIGHT Copyright \(co 2008 Free Software Foundation. .br Permission is granted to make and distribute verbatim copies of this manual provided the copyright notice and this permission notice are preserved on all copies. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
