                        fprintf(stderr, "failed to ignore signal SIGPIPE !\n"); \

        } while (0)

Initialize dump system.

Parameters

[in]

args

Generally use NULL as input. Ignore SIGPIPE to avoid program stop after pipe destoryed.

Function Documentation

INT32 _VFTR_initDump

(

char *

args

)

Initialize dump system for debugging.

Parameters

[in]

args

Generally use NULL as input.

INT32 VFTR_dump	(	const VOID *	buf,
		UINT32	len,
		UINT32	flag,
		TIMESPEC_S	timestamp
	)

Dump a data structure with timestamps.

Parameters

[in]	buf	Data to be sent
[in]	len	Length of data
[in]	timestamp	Better to be a wall clock which matches the OSD timestamp shown in video clips

Returns

0 if success, otherwise, a negative value returns

TIMESPEC_S

INT32 VFTR_dumpWithJiffies	(	const VOID *	buf,
		UINT32	len,
		UINT32	flag,
		UINT32	jiffies
	)

A jiffies version of VFTR_dump.

Parameters

[in]	buf	Data to be sent
[in]	len	Length of data
[in]	jiffies	You can use U32 timestamp in MPI_IVA_OBJ_LIST_S

Returns

0 if success, otherwise, a negative value returns
