Function Documentation

rtnl_tc_handle2str()

char * rtnl_tc_handle2str	(	uint32_t	handle,
		char *	buf,
		size_t	len
	)

Convert a traffic control handle to a character string (Reentrant).

Parameters

handle	traffic control handle
buf	destination buffer
len	buffer length

Converts a tarffic control handle to a character string in the form of MAJ:MIN and stores it in the specified destination buffer.

Returns

The destination buffer or the type encoded in hexidecimal form if no match was found.

rtnl_tc_str2handle()

int rtnl_tc_str2handle	(	const char *	str,
		uint32_t *	res
	)

Convert a charactering strint to a traffic control handle.

Parameters

str	traffic control handle as character string
res	destination buffer

Converts the provided character string specifying a traffic control handle to the corresponding numeric value.

The handle must be provided in one of the following formats:

• NAME
• root
• none
