Detailed Description

This module includes functions that allow a Host processor to execute remote procedure calls on a co-processor over spinel.

Function Documentation

◆ otCliAppendResult()

void otCliAppendResult ( otError aError )

Append an error code to the output buffer.

Parameters
[in] aError

◆ otCliOutputBytes()

void otCliOutputBytes ( const uint8_t * aBytes,
uint8_t aLength
)

Output a byte array as hex to the output buffer.

Parameters
[in] aBytes Bytes to output
[in] aLength Number of bytes

◆ otCliOutputCommands()

void otCliOutputCommands ( const otCliCommand aCommands[],
size_t aCommandsLength
)

Write all command names in aCommands to the output buffer.

Parameters
[in] aCommands an array of commands
[in] aCommandsLength length of aCommands

◆ otCliOutputFormat()

void otCliOutputFormat ( const char * aFmt,
...
)

Write formatted string to the output buffer.

Parameters
[in] aFmt A pointer to the format string.
[in] ... A matching list of arguments.

◆ otCliOutputFormatV()

int otCliOutputFormatV ( const char * aFormat,
va_list aArguments
)

Write formatted output to the output buffer.

Parameters
[in] aFormat A pointer to the format string.
[in] aArguments A variable list of arguments for format.
Returns
The number of bytes placed in the output buffer.

◆ otCliOutputIp6Address()

int otCliOutputIp6Address ( const otIp6Address * aAddress )

Write an IPv6 address to the output buffer.

Parameters
[in] aAddress A pointer to the IPv6 address.
Returns
The number of bytes placed in the output queue.
Return values
-1 Driver is broken.

◆ otCliSetUserCommandError()

void otCliSetUserCommandError ( otError aError )

This method sets the user command error.

Parameters
[in] aError An error

◆ otCRPCHandleCommand()

otError otCRPCHandleCommand ( void * aContext,
uint8_t aArgsLength,
char * aArgs[],
uint8_t aCommandsLength,
const otCliCommand aCommands[]
)

Call the corresponding handler for a command.

This function will look through aCommands to find a command that matches aArgs [0]. If found, the handler function for the command will be called with the remaining args passed to it.

Parameters
