Detailed Description

Declares entities to handle return status codes used in VPI.

VPI functions uses status codes to return if they succeeded or not.

Macro Definition Documentation

VPI_MAX_STATUS_MESSAGE_LENGTH

#define VPI_MAX_STATUS_MESSAGE_LENGTH   256

#include </opt/nvidia/vpi2/include/vpi/Status.h>

Maximum status message length in bytes.

This is the maximum number of bytes that will be written by vpiGetLastStatusMessage and vpiPeekAtLastStatusMessage to the status message output buffer.

Function Documentation

vpiStatusGetName()

const char* vpiStatusGetName

(

VPIStatus

code

)

#include </opt/nvidia/vpi2/include/vpi/Status.h>

Returns a string representation of the status code.

Parameters

[in]

code

Status code whose string representation is to be returned.

Returns

The string representation of the status code. Returned string is valid until next call of this function from the same calling thread. Returned pointer must not be freed.

vpiGetLastStatus()

VPIStatus vpiGetLastStatus

(

)

#include </opt/nvidia/vpi2/include/vpi/Status.h>

Returns and resets the status of the last VPI function call in current thread.

A new call to this function will return VPI_SUCCESS, as the thread-specific status was reset. This operation doesn't affect the statuses in other threads.

Returns

The status of the last VPI function call in current thread.

vpiGetLastStatusMessage()

VPIStatus vpiGetLastStatusMessage	(	char *	msgBuffer,
		int32_t	lenBuffer
	)

#include </opt/nvidia/vpi2/include/vpi/Status.h>

Returns and resets the status code and message of the last VPI function call in current thread.

A new call to this function will return VPI_SUCCESS, as the thread-specific status was reset. This operation doesn't affect the status in other threads.

It's guaranteed that the message is never larger than VPI_MAX_STATUS_MESSAGE_LENGTH bytes, including the '\0' string terminator.

Parameters

[out]	msgBuffer	Pointer to memory where the status message will be written to. If NULL, no message is returned.
[in]	lenBuffer	Size in bytes of msgBuffer. If less than zero, lenBuffer is assumed to be 0.

Returns

The status of the last VPI function call in current thread.

vpiPeekAtLastStatus()

VPIStatus vpiPeekAtLastStatus

(

)

#include </opt/nvidia/vpi2/include/vpi/Status.h>

Returns the status of the last VPI function call in current thread.

The status code won't be reset.

Returns

The status of the last VPI function call in current thread.

vpiPeekAtLastStatusMessage()

VPIStatus vpiPeekAtLastStatusMessage	(	char *	msgBuffer,
		int32_t	lenBuffer
	)

#include </opt/nvidia/vpi2/include/vpi/Status.h>

Returns and status code and message of the last VPI function call in current thread.

The status code and message won't be reset.

It's guaranteed that the message is never larger than VPI_MAX_STATUS_MESSAGE_LENGTH bytes, including the '\0' string terminator.

Parameters

[out]	msgBuffer	Pointer to memory where the status message will be written to. If NULL, no message is returned.
[in]	lenBuffer	Size in bytes of msgBuffer. If less than zero, lenBuffer is assumed to be 0.

Returns

The status of the last VPI function call in current thread.
