cp_client_create_ssl(3) - Linux man page

Name

cp_client_create, cp_client_create_ssl - create a tcp client

Synopsis

#include <cprops/client.h>

cp_client *cp_client_create(char *host, int port);
cp_client *cp_client_create_ssl(char *host, int port,

char *CA_file, char *CA_directory, int verification_mode);

Description

cp_client_create creates a cp_client structure to be used to connect to the given host on the given port. The call will fail if the requested host name could not be resolved, or if internal allocations fail.

cp_client_create_ssl does the same, but in addition attempts to initialize an SSL_CTX object based on the given CA_file or CA_directory - one of which must be specified. Certificates may be read from a directory containing trusted certificate authority certificates in PEM format using the CA_directory, or from a file specified by CA_file. See SSL_CTX_load_verify_locations (3) for more on certificate files.
verification_mode should be either SSL_VERIFY_NONE if a connection should be established even if the server certificate cannot be verified, or SSL_VERIFY_PEER to fail the connection on verification failure.

Once a cp_client structure has been successfully created, cp_client_connect may be called to establish a connection.

cp_client object created with cp_client_create or cp_client_create_ssl should be finalized by calling cp_client_destroy.

Return Value

the newly created cp_client structure on success or NULL on failure.
