Functions ¶
func FindEPConfigCHeader ¶
FindEPConfigCHeader returns the full path of the file that is the CHeaderFileName from the slice of files
func FmtDefineAddress ¶
FmtDefineAddress returns the a define string from the given name and addr. Example: fmt.Print(FmtDefineAddress("foo", []byte{1, 2, 3})) // "#define foo { .addr = { 0x1, 0x2, 0x3 } }\n"
func FmtDefineArray ¶
FmtDefineArray returns the a define string from the given name and array. Example: fmt.Print(FmtDefineArray("foo", []byte{1, 2, 3})) // "#define foo { 0x1, 0x2, 0x3 }\n"
func FmtDefineComma ¶ added in v0.9.0
func GetCiliumVersionString ¶
GetCiliumVersionString returns the first line containing CiliumCHeaderPrefix.
func GetGroupIDByName ¶
GetGroupIDByName returns the group ID for the given grpName.
func RequireRootPrivilege ¶ added in v0.9.0
func RequireRootPrivilege(cmd string)
RequireRootPrivilege checks if the user running cmd is root. If not, it exits the program
func SetupLogging ¶ added in v0.9.0
SetupLogging sets up each logging service provided in loggers and configures each logger with the provided logOpts.
Types ¶
type MapOptions ¶ added in v0.9.0
type MapOptions struct {
// contains filtered or unexported fields
}
MapOptions holds a map of values and a validation function.
func NewMapOpts ¶ added in v0.9.0
func NewMapOpts(values map[string]string, validator Validator) *MapOptions
NewMapOpts creates a new MapOpts with the specified map of values and an optional validator.
func (*MapOptions) Set ¶ added in v0.9.0
func (opts *MapOptions) Set(value string) error
Set validates, if needed, the input value and adds it to the internal map, by splitting on '='.
func (*MapOptions) String ¶ added in v0.9.0
func (opts *MapOptions) String() string
func (*MapOptions) Type ¶ added in v0.9.0
func (opts *MapOptions) Type() string
Type returns a string name for this Option type
type NamedMapOptions ¶ added in v0.9.0
type NamedMapOptions struct { MapOptions // contains filtered or unexported fields }
NamedMapOptions is a MapOptions struct with a configuration name. This struct is useful to keep reference to the assigned field name in the internal configuration struct.
func NewNamedMapOptions ¶ added in v0.9.0
func NewNamedMapOptions(name string, values *map[string]string, validator Validator) *NamedMapOptions
NewNamedMapOptions creates a reference to a new NamedMapOpts struct.
