I am trying to make a server and client, the client will choose between some options and the server will react accordingly.
After a some reads and writes that work the server needs to read from client an INT i use this:
But even if all the other times there was no problem
this time the server does not seem to block on read OR it reads something but without the client sending.I also wrote multiple reads in server after this one and no writes in client, still the server passed through them to the next lines of code.
How can 'popen()' be used for reading and writing to opening pipe?
If i try 'popen("prog", "rw")'
and then put and get chars - it does
not work.
What is wrong? (1 Reply)

SSL_get_client_CA_list(3) OpenSSL SSL_get_client_CA_list(3)NAME
SSL_get_client_CA_list, SSL_CTX_get_client_CA_list - get list of client CAs
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include <openssl/ssl.h>
STACK_OF(X509_NAME) *SSL_get_client_CA_list(const SSL *s);
STACK_OF(X509_NAME) *SSL_CTX_get_client_CA_list(const SSL_CTX *ctx);
DESCRIPTION
SSL_CTX_get_client_CA_list() returns the list of client CAs explicitly set for ctx using SSL_CTX_set_client_CA_list(3).
SSL_get_client_CA_list() returns the list of client CAs explicitly set for ssl using SSL_set_client_CA_list() or ssl's SSL_CTX object with
SSL_CTX_set_client_CA_list(3), when in server mode. In client mode, SSL_get_client_CA_list returns the list of client CAs sent from the
server, if any.
RETURN VALUES
SSL_CTX_set_client_CA_list() and SSL_set_client_CA_list() do not return diagnostic information.
SSL_CTX_add_client_CA() and SSL_add_client_CA() have the following return values:
STACK_OF(X509_NAMES)
List of CA names explicitly set (for ctx or in server mode) or send by the server (client mode).
NULL
No client CA list was explicitly set (for ctx or in server mode) or the server did not send a list of CAs (client mode).
