Detailed Description

These modules provide an interface for text based applications.

The functions provided are wrappers for their libnl equivalent with added error handling. The functions check for allocation failures, invalid input, and unknown types and will print error messages accordingly via nl_cli_fatal().

Function Documentation

◆ nl_cli_parse_u32()

uint32_t nl_cli_parse_u32 ( const char * arg )

Parse a text based 32 bit unsigned integer argument.

Parameters

arg	Integer in text form.

Tries to convert the number provided in arg to a uint32_t. Will call nl_cli_fatal() if the conversion fails.

Returns: 32bit unsigned integer.
