The SSL_read function reads application data from a Secure Sockets Layer (SSL) session.
Format
#include <openssl/ssl.h> int SSL_read(SSL *ssl,char *buf,int num)
Normal Return
Returns the number of bytes of data (from 1 to the value specified on the num parameter) that are read.
Error Return
A return code equal to 0 or a negative number indicates an error. Issue the SSL_get_error function to obtain specific information about the error.
Programming Considerations
If this is a shared SSL session, the socket will be changed to nonblocking mode when the SSL_read function is completed.
