Function Documentation

save_trace_names()

size_t save_trace_names	(	void *	dest,
		const char **	names,
		int	nnames
	)

Save a name mapping table to a memory location, and/or compute the size of the storage for the mapping table.

Parameters

dest	Where to save the name mapping table. If this is NULL, the table will not be saved, but the size required to store the table will be returned.
names	The names in the name mapping table.
nnames	The number of names in the name mapping table.

Returns

The size of the table, in bytes, rounded up to 8 bytes.

Variable Documentation

default_group_details

const sw_tracegroup_t default_group_details[]

static

Default Group details struct.

This is used to construct detailed usage messages. The usage message is constructed using a function so that re-ordering names in the core doesn't cause the skin to be out of order.

Can be overridden when calling the init function.

default_trace_enabled

int default_trace_enabled[SKINKIT_TRACE_N]

static

Default array for trace enabled/disabled state.

default_trace_name

const char* default_trace_name[SKINKIT_TRACE_N]

static

Initial value:

= {
  NULL, 
 
  NULL, 
 
}

Default trace name array

default_tracetype_name

const char* default_tracetype_name[SKINKIT_TRACETYPE_N]

static

Initial value:

= {
  NULL, 
 
  NULL, 
 
}

Default trace type name array

g_nTraceNames

int g_nTraceNames = SKINKIT_TRACE_N

Number of trace names in trace name array

g_nTraceTypeNames

int g_nTraceTypeNames = SKINKIT_TRACETYPE_N

Number of trace type names in trace type list

g_pabTraceEnabled

int* g_pabTraceEnabled = &default_trace_enabled[0]

This pointer will point to either the default enabled/disable state array, or an array that was specified in the init function.

g_ppTraceNames

const char** g_ppTraceNames = &default_trace_name[0]

This pointer will point to either the default trace name array, or an array that was specified in the init function.

g_ppTraceTypeNames

const char** g_ppTraceTypeNames = &default_tracetype_name[0]

This pointer will point to either the default trace type name array, or an array that was specified in the init function.
