| =head1 NAME
 | |
| 
 | |
| BIO_hostserv_priorities,
 | |
| BIO_parse_hostserv
 | |
| - utility routines to parse a standard host and service string
 | |
| 
 | |
| =head1 SYNOPSIS
 | |
| 
 | |
|  #include <openssl/bio.h>
 | |
| 
 | |
|  enum BIO_hostserv_priorities {
 | |
|      BIO_PARSE_PRIO_HOST, BIO_PARSE_PRIO_SERV
 | |
|  };
 | |
|  int BIO_parse_hostserv(const char *hostserv, char **host, char **service,
 | |
|                         enum BIO_hostserv_priorities hostserv_prio);
 | |
| 
 | |
| =head1 DESCRIPTION
 | |
| 
 | |
| BIO_parse_hostserv() will parse the information given in B<hostserv>,
 | |
| create strings with the host name and service name and give those
 | |
| back via B<host> and B<service>.  Those will need to be freed after
 | |
| they are used.  B<hostserv_prio> helps determine if B<hostserv> shall
 | |
| be interpreted primarily as a host name or a service name in ambiguous
 | |
| cases.
 | |
| 
 | |
| The syntax the BIO_parse_hostserv() recognises is:
 | |
| 
 | |
|  host + ':' + service
 | |
|  host + ':' + '*'
 | |
|  host + ':'
 | |
|         ':' + service
 | |
|  '*'  + ':' + service
 | |
|  host
 | |
|  service
 | |
| 
 | |
| The host part can be a name or an IP address.  If it's a IPv6
 | |
| address, it MUST be enclosed in brackets, such as '[::1]'.
 | |
| 
 | |
| The service part can  be a service name or its port number.
 | |
| 
 | |
| The returned values will depend on the given B<hostserv> string
 | |
| and B<hostserv_prio>, as follows:
 | |
| 
 | |
|  host + ':' + service  => *host = "host", *service = "service"
 | |
|  host + ':' + '*'      => *host = "host", *service = NULL
 | |
|  host + ':'            => *host = "host", *service = NULL
 | |
|         ':' + service  => *host = NULL, *service = "service"
 | |
|   '*' + ':' + service  => *host = NULL, *service = "service"
 | |
| 
 | |
|  in case no ':' is present in the string, the result depends on
 | |
|  hostserv_prio, as follows:
 | |
| 
 | |
|  when hostserv_prio == BIO_PARSE_PRIO_HOST
 | |
|  host                 => *host = "host", *service untouched
 | |
| 
 | |
|  when hostserv_prio == BIO_PARSE_PRIO_SERV
 | |
|  service              => *host untouched, *service = "service"
 | |
| 
 | |
| =head1 RETURN VALUES
 | |
| 
 | |
| BIO_parse_hostserv() returns 1 on success or 0 on error.
