The -.Nm -library contains routines to extract the -.Em report descriptor -which contains the data layout information and then use this information. -.Pp -The routines can be divided into four parts: extraction of the descriptor, -parsing of the descriptor, translating to/from symbolic names, and -data manipulation. -.Ss DESCRIPTOR FUNCTIONS -A report descriptor can be obtained by calling -.Fn hid_get_report_desc -with a file descriptor obtained by opening a -.Xr uhid 4 -device. -When the report descriptor is no longer needed it should be freed -by calling -.Fn hid_dispose_report_desc . -The type -.Fa report_desc_t -is opaque and should be used when calling the parsing functions. -.Ss DESCRIPTOR PARSING FUNCTIONS -To parse the report descriptor the -.Fn hid_start_parse -function should be called with a report descriptor and a set that -describes which items that are interesting. The set is obtained -by oring together values -.Fa "(1 << k)" -where -.Fa k -is an item of type -.Fa hid_kind_t . -The function returns -.Fa NULL -if the initialization fails, otherwise an opaque value to be used -in subsequent calls. -After parsing the -.Fn hid_end_parse -function should be called to free internal data structures. -.Pp -To iterate through all the items in the report descriptor -.Fn hid_get_item -should be called while it returns a value greater than 0. -When the report descriptor ends it will returns 0; a syntax -error within the report descriptor will cause a return value less -than 0. -The struct pointed to by -.Fa h -will be filled with the relevant data for the item. -The definition of -.Fa hid_item_t -can be found in -.Pa <usb.h> -and the meaning of the components in the USB HID documentation. -.Pp -Data should be read/written to the device in the size of -the report. The size of a report (of a certain kind) can be -computed by the -.Fn hid_report_size -function. If the report is prefixed by an ID byte it is -stored at -.Fa idp , -otherwise it will contain 0. -.Pp -To locate a single item the -.Fn hid_locate -function can be used. It should be given the usage code of -the item and its kind and it will fill the item and return -non-zero if the item was found. -.Pp -.Ss NAME TRANSLATION FUNCTIONS -The function -.Fn hid_usage_page -will return the symbolic name of a usage page, and the function -.Fn hid_usage_in_page -will return the symbolic name of the usage within the page. -Both these functions may return a pointer to static data. -Before either of these functions can be called the usage table -must be parsed, this is done by calling -.Fn hid_init -with the name of the table. Passing -.Fa NULL -to this function will cause it to use the default table. -.Ss DATA EXTRACTION FUNCTIONS -Given the data obtained from a HID device and an item in the -report descriptor the -.Fn hid_get_data -function extracts the value of the item. -Conversely -.Fn hid_set_data -can be used to put data into a report (which must be zeroed first). -.Sh EXAMPLE -Not yet. -.Sh FILES -.Pa /usr/share/misc/usb_hid_usages -The default HID usage table. -.Sh BUGS -This man page is woefully incomplete. -.Sh SEE ALSO -The -.Tn USB -specifications can be found at -.Dv http://www.usb.org/developers/docs.htm . -.Pp -.Xr hid 4 , -.Xr usb 4 . -.Sh HISTORY -The -.Nm -library first appeared in -.Nx 1.5 . |
