consists of a number of functions designed to aid in + interacting with the + .Xr sa 4 + driver. + The + .Xr sa 4 + driver returns some status data as XML-formatted strings, and + the primary purpose of this library is to make it easier for the + software developer to parse those strings and extract the status values. + .Pp + The + .Fn mt_start_element , + .Fn mt_end_element , + and + .Fn mt_char_handler + functions are designed to work with the + .Xr libbbsdxml 3 + library, which is an XML parsing library. + The user data for the XML parser should be set with + .Fn XML_SetUserData + to a zeroed struct + mt_status_data with the entries list initialized. + The element handlers for the XML parser should be set to + .Fn mt_start_element + and + .Fn mt_end_element + with + .Fn XML_SetElementHandler . + The character data handler should be set to + .Fn mt_char_handler + with the + .Fn XML_SetCharacterDataHandler + function. + The error member of the status_data structure will be set to 0 if parsing + is successful, and non-zero if parsing failed. + In the event of a failure, the error_str member will contain an error + message describing the failure. + These functions will build a tree of tape driver status data that can be + searched and printed using the other functions in this library. + .Pp + .Fn mt_status_tree_sbuf + takes the root node of a tree of + .Xr sa 4 + driver status information, and displays it in an + .Xr sbuf 9 . + The + .Ar sb + argument is the destination sbuf. + The + .Ar entry + argument is the root of the tree. + The + .Ar indent + argument is the number of characters to indent the output. + Each recursive call to + .Fn mt_status_tree_sbuf + will have the indent level incremented by 2. + The + .Ar sbuf_func + argument is for a user-supplied alternate printing function. + If it is non-NULL, it will be called instead of the default output printing + code. + The + .Ar arg + argument is an argument for the + .Ar sbuf_func + function. + .Pp + The + .Fn mt_status_tree_print + function is the same as the + .Fn mt_status_tree_sbuf + function, except that the tree is printed to standard out instead of to a + sbuf. + .Pp + The + .Fn mt_entry_find + function returns the first entry in the tree starting at + .Ar entry + that matches + .Ar name . + The supplied node name can be a single level name like "foo", or it can + specify mulitple node names that must be matched, for instance "foo.bar.baz". + In the case of a single level name, it will match any node beneath + .Ar entry + that matches + .Ar name . + In the case of a multi-level name like "foo.bar.baz", it will return the + first entry named "baz" whose immediate parent is "bar" and where the + parent of "bar" is named "foo". + .Pp + The + .Fn mt_status_entry_find + is the same as + .Fn mt_entry_find , + except that it operates on the top level mt_status_data and all + mt_status_entry nodes below it instead of just an mt_status_entry + structure. + .Pp + The + .Fn mt_status_entry_free + function frees the tree of status data underneath + .Ar entry . + .Pp + The + .Fn mt_status_free + function frees the tree of status data underneath + .Ar status_data . + .Pp + The + .Fn mt_entry_sbuf + function prints + .Ar entry + to the supplied sbuf + .Ar sb , + optionally using the + .Xr printf 3 + format + .Ar fmt . + If + .Ar fmt + is NULL, then + .Fn mt_entry_sbuf + will render integer types in base 10 without special formatting and all + other types as they were rendered in the XML. + .Pp + .Fn mt_param_parent_sbuf + prints the parents of the given + .Ar entry + to the supplied sbuf + .Ar sb + subject to the print parameters + .Ar print_params . + The result will be formatted with a period between each level, like + "foo.bar.baz". + .Pp + .Fn mt_param_parent_print + is like + .Fn mt_param_parent_sbuf + except that it prints the results to standard output instead of an sbuf. + .Pp + .Fn mt_param_entry_sbuf + prints the + .Ar entry + to the given sbuf + .Ar sb . + The argument + .Ar arg + is a pointer to struct mt_print_params, which allows the caller to control + the printing output. + This function is intended to be supplied as an argument to + .Fn mt_status_tree_sbuf . + .Pp + .Fn mt_param_entry_print + is like + .Fn mt_param_entry_sbuf + except that it prints to standard output instead of an sbuf. + It is intended to be used as an argument to + .Fn mt_status_tree_print . + .Pp + .Fn mt_protect_print + prints tape drive protection information from the supplied + .Ar status_data + beginning at the node name defined as the root node for protection data. + If the + .Ar verbose + argument is non-zero, protection entry descriptions will be printed. + If it is zero, protection entry descriptions will not be printed. + .Pp + .Fn mt_param_list + prints tape driver parameters information from the supplied + .Ar status_data . + If the + .Ar param_name + is non-NULL, only the named parameter will be printed. + If + .Ar quiet + is non-zero, parameter descriptions will be omitted in the output. + .Pp + .Fn mt_density_name + Returns a text identifier for the supplied numeric + .Ar density_num . + The + .Ar density_num + should currently be a value between 0 and 255 inclusive, since that is the + valid range for + .Tn SCSI + density code values. + See below for notes on the return values. + .Pp + .Fn mt_density_bp + Returns the bits per inch or bits per mm values for a given density entry + specified by the + .Ar density_num . + If the + .Ar bpi + argument is non-zero, the bits per inch value is returned. + Otherwise, the bits per mm value is returned. + .Pp + .Fn mt_density_num + returns a numeric value for a text density description. + It does a case-insensitive comparison of density names in the density table + to the supplied density name. + .Pp + .Fn mt_get_xml_str + gets the current XML status / parameter string from the sa(4) driver + instance referenced by the open file descriptor + .Ar mtfd . + The + .Xr mtio 4 + .Xr ioctl 2 + to be used is supplied as the + .Ar cmd + argument. + Currently the + .Fn mt_get_xml_str + function will work with the + .Dv MTIOCEXTGET + and + .Dv MTIOCPARAMGET + ioctls. + The supplied + .Ar xml_str + will be filled in with a pointer to the complete XML status string. + Multiple calls to the given + .Xr ioctl 2 + are made and more space is malloced until all of the XML string is fetched. + The string returned in the + .Ar xml_str + argument should be freed when it is no longer in use. + .Sh RETURN VALUES + .Fn mt_entry_find + returns the first matching entry, or NULL if it fails to find a match. + .Pp + .Fn mt_status_entry_find + returns the first matching entry, or NULL if it fails to find a match. + .Pp + .Fn mt_protect_print + Returns 0 for success, and non-zero for failure. + .Fn mt_protect_print + can only fail if it cannot find protection information in the supplied + status data. + .Pp + .Fn mt_param_list + Returns 0 for success and non-zero for failure. + .Fn mt_param_list + can only fail if it cannot find parameter information in the supplied + status data. + .Pp + .Fn mt_density_name + returns a text description of a numeric density. + The special density value 0 is decoded as "default". + The special density value 0x7f is decoded as "same". + If the density is not known, + .Fn mt_density_name + will return "UNKNOWN". + .Pp + .Fn mt_density_bp + returns the bits per inch value for the given density (if the + .Ar bpi + field is non-zero), the bits per mm value otherwise, or 0 if the supplied + .Ar density_num + is not in the density table or the table entry does not include bpi / bpmm + values. + .Pp + .Fn mt_density_num + returns a numeric density value between 0 and 255 for the supplied density + name. + It returns 0 if the density name is not recognized. + .Pp + .Fn mt_get_xml_str + returns 0 for success, and -1 for failure. + .Sh SEE ALSO + .Xr mt 1 , + .Xr mtio 4 , + .Xr sa 4 +
