index entries marked with X<> in POD. Of course, you'll have to process
the output yourself in some meaningful fashion.

SSL_load_client_CA_file 3 "0.9.7" "2003-01-13" "OpenSSL"
C "NAME"
SSL_load_client_CA_file - load certificate names from file
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1
#include <openssl/ssl.h>
.Ve
.Vb 1
STACK_OF(X509_NAME) *SSL_load_client_CA_file(const char *file);
.Ve
"DESCRIPTION"
Header "DESCRIPTION" \fISSL_load_client_CA_file() reads certificates from file and returns
a STACK_OF(X509_NAME) with the subject names found.
"NOTES"
Header "NOTES" \fISSL_load_client_CA_file() reads a file of \s-1PEM\s0 formatted certificates and
extracts the X509_NAMES of the certificates found. While the name suggests
the specific usage as support function for
SSL_CTX_set_client_CA_list(3),
it is not limited to \s-1CA\s0 certificates.
"EXAMPLES"
Header "EXAMPLES" Load names of CAs from file and use it as a client \s-1CA\s0 list:
.Vb 2 SSL_CTX *ctx; STACK_OF(X509_NAME) *cert_names; .Ve .Vb 7 ... cert_names = SSL_load_client_CA_file("/path/to/CAfile.pem"); if (cert_names != NULL) SSL_CTX_set_client_CA_list(ctx, cert_names); else error_handling(); ... .Ve
"RETURN VALUES"
Header "RETURN VALUES" The following return values can occur:
p "\s-1NULL\s0" 4 Item "NULL" The operation failed, check out the error stack for the reason.
p "Pointer to STACK_OF(X509_NAME)" 4 Item "Pointer to STACK_OF(X509_NAME)" Pointer to the subject names of the successfully read certificates.
"SEE ALSO"
Header "SEE ALSO" ssl(3),
SSL_CTX_set_client_CA_list(3)
