Types

type GreaseError 

type GreaseError struct {
	Str   string
	Errno int
}

GreaseError is used for error reporting from greaseLib, and is analagous to the same structure in the C library. An errornum of 0 means 'no error'

func ConvertCGreaseError 

func ConvertCGreaseError(err *C.GreaseLibError) *GreaseError

type GreaseIdMap 

type GreaseIdMap map[string]uint32
var DefaultLevelMap GreaseIdMap
var DefaultTagMap GreaseIdMap
var TargetMap GreaseIdMap

[string]:[target ID]

type GreaseLevel 

type GreaseLevel uint32
const GREASE_ALL_LEVELS GreaseLevel = 0xFFFFFFFF //C.GREASE_ALL_LEVELS

type GreaseLib 

type GreaseLib struct {
	// contains filtered or unexported fields
}

The GreaseLib structure represents a single instantiation of the library. For now, only one instantiation is supported.

type GreaseLibAddTargetCB 

type GreaseLibAddTargetCB func(err *GreaseError, optsId int, targId uint32)

Callback used for a callback which

type GreaseLibCallbackEvent 

type GreaseLibCallbackEvent struct {
	// contains filtered or unexported fields
}

type GreaseLibCallbackNoData 

type GreaseLibCallbackNoData interface {
	// contains filtered or unexported methods
}

This generic interfaces represents places in the greaseLib where the C GreaseLibCallback(err,void *) is used, but no data is ever passed back with the void pointer

type GreaseLibFilter 

type GreaseLibFilter struct {
	Origin uint32
	Tag    uint32
	Target uint32
	Mask   uint32

	//	_enabledFlags uint32
	//	origin uint32
	//	tag uint32
	//	target uint32
	//	mask uint32
	//	id uint32
	Format_pre          *string
	Format_post         *string
	Format_post_pre_msg *string
	// contains filtered or unexported fields
}

func NewGreaseLibFilter 

func NewGreaseLibFilter() *GreaseLibFilter

type GreaseLibProcessClosedRedirectCallback 

type GreaseLibProcessClosedRedirectCallback func(err *GreaseError, stream_type int, pid int)

type GreaseLibSink 

type GreaseLibSink struct {
	// contains filtered or unexported fields
}

func NewGreaseLibSink 

func NewGreaseLibSink(sinkType uint32, path *string) *GreaseLibSink

type GreaseLibStartCB 

type GreaseLibStartCB func()

This interface is for providing a special callback to called when the greaseLib starts

type GreaseLibTargetCB 

type GreaseLibTargetCB func(err *GreaseError, data *TargetCallbackData)

This interface is used for a 'callback target' in go. The greaseLibCallback(err,data) will be called with a 'data' string representing all log data since the last callback

type GreaseLibTargetFileOpts 

type GreaseLibTargetFileOpts struct {
	Mode            uint32 // permissions for file (recommend default)
	Flags           uint32 // file flags (recommend default)
	Max_files       uint32 // max # of files to maintain (rotation)
	Max_file_size   uint32 // max size for any one file
	Max_total_size  uint64 // max total size to maintain in rotation
	Rotate_on_start bool
	// contains filtered or unexported fields
}

type GreaseLibTargetOpts 

type GreaseLibTargetOpts struct {
	Delim          *string
	TTY            *string
	File           *string
	OptsId         int                      // filled in automatically
	TargetCB       GreaseLibTargetCB        // used if this is target is a callback
	FileOpts       *GreaseLibTargetFileOpts // nil if not used
	Format_pre     *string
	Format_time    *string
	Format_level   *string
	Format_tag     *string
	Format_origin  *string
	Format_post    *string
	Format_pre_msg *string
	Name           *string // not used by greaseLib - but used for a string reference name

	NumBanks uint32
	// contains filtered or unexported fields
}

analgous to greaseLib GreaseLibTargetOpts

func NewGreaseLibTargetOpts 

func NewGreaseLibTargetOpts() *GreaseLibTargetOpts

type TargetCallbackData 

type TargetCallbackData struct {
	// contains filtered or unexported fields
}

func (*TargetCallbackData) GetBufferAsSlice 

func (data *TargetCallbackData) GetBufferAsSlice() []byte
