NAME

       ax25_aton,   ax25_aton_entry,  ax25_aton_arglist,  ax25_ntoa,  ax25_cmp,  ax25_validate  -  AX25  Address
       manipulation routines

SYNOPSIS

       #include <netax25/ax25.h>

       int ax25_aton(const char *cp, struct full_sockaddr_ax25 *fsap);

       int ax25_aton_arglist(const char **cp, struct full_sockaddr_ax25 *fsap);

       int ax25_aton_entry(const char *cp, char *axp);

       char *ax25_ntoa(ax25_address *axp);

       int ax25_cmp(ax25_address *ax1, ax25_address *ax2);

       int ax25_validate(char *axp);

       char *ax25_config_file(const char *filename);

DESCRIPTION

       ax25_aton() takes the ASCII string cp that is in the format callsign [[V|VIA]callsign...]  and stores  it
       in fsap in network format.

       ax25_aton_entry() takes the ASCII string of a callsign cp and stores it in network format in axp.

       The  ax25_aton_arglist()  takes  a  NULL  terminated array of strings cp and stores it in fsap in network
       format.

       The ax25_ntoa() takes a network format address axp and returns the ASCII representation.  The  string  is
       returned in a statically allocated buffer, which subsequent calls will overwrite.

       The  ax25_cmp()  function  compares  the  two ax25 addresses, ax1 and ax2, that are in network format and
       determines whether they are identical, differ only by their SSIDs or are different.

       The ax25_validate() function checks to see if the address axp in network format is a correctly  formatted
       address.

RETURN VALUE

       The ax25_aton()and ax25_aton_arglist() functions return -1 if an error occurs otherwise the length of the
       returned structure.

       The ax25_aton_entry() function returns -1 if an error occurs otherwise zero.

       The ax25_cmp() function returns 0 if the two addresses are identical, 1 if they are  different  or  2  is
       only the SSIDs are different.

       The ax25_validate() function returns TRUE if the callsign is valid or FALSE if it is not.
