Functions

vc_gencmd_read_response^⚠

NAME vc_gencmd_read_response

vc_gencmd_send^⚠

Send commands to VideoCore. These all return 0 for success. They return VC_MSGFIFO_FIFO_FULL if there is insufficient space for the whole message in the fifo, and none of the message is sent.

vc_gencmd_stop^⚠

NAME vc_gencmd_stop

vc_vchi_gencmd_init^⚠

NAME vc_vchi_gencmd_init

vchi_connect^⚠

vchi_disconnect^⚠

vchi_initialise^⚠

vcos_deinit^⚠

vcos deinitialization. Call this function when vcos is no longer required, in order to free resources. Calls can be nested within the same process; they are reference counted so that only a call that decrements the reference count to 0 has any effect. @note On platforms/toolchains that support it, gcc’s destructor attribute or similar is used to invoke this function after exit() or equivalent. @return Status of initialisation.

vcos_init^⚠

vcos initialization. Call this function before using other vcos functions. Calls can be nested within the same process; they are reference counted so that only a call from uninitialized state has any effect. @note On platforms/toolchains that support it, gcc’s constructor attribute or similar is used to invoke this function before main() or equivalent. @return Status of initialisation.
