NAME

       SDL_hid_send_feature_report - Send a Feature report to the device.

HEADER FILE

       Defined in SDL3/SDL_hidapi.h

SYNOPSIS

       #include "SDL3/SDL.h"

       int SDL_hid_send_feature_report(SDL_hid_device *dev, const unsigned char *data, size_t length);

DESCRIPTION

       Feature  reports are sent over the Control endpoint as a Set_Report transfer. The first byte of data must
       contain the Report ID. For devices which only support a single report, this  must  be  set  to  0x0.  The
       remaining bytes contain the report data. Since the Report ID is mandatory, calls to

       SDL_hid_send_feature_report  ()  will always contain one more byte than the report contains. For example,
       if a hid report is 16 bytes long, 17 bytes must be passed to

       SDL_hid_send_feature_report (): the Report ID (or 0x0, for devices which do not  use  numbered  reports),
       followed by the report data (16 bytes). In this example, the length passed in would be 17.

FUNCTION PARAMETERS

       dev    a device handle returned from SDL_hid_open ().

       data   the data to send, including the report number as the first byte.

       length the length in bytes of the data to send, including the report number.

RETURN VALUE

       Returns the actual number of bytes written and -1 on failure; call

       SDL_GetError () for more information.

AVAILABILITY

       This function is available since SDL 3.2.0.
