The main tracing object
gboolean gst_alloc_trace_available (void);
Check if alloc tracing was commiled into the core
Returns : | TRUE if the core was compiled with alloc tracing enabled. |
const GList* gst_alloc_trace_list (void);
Get a list of all registered alloc trace objects.
Returns : | a GList of GstAllocTrace objects. |
int gst_alloc_trace_live_all (void);
Get the total number of live registered alloc trace objects.
Returns : | the total number of live registered alloc trace objects. |
void gst_alloc_trace_print_all (void);
Print the status of all registered alloc trace objects.
void gst_alloc_trace_set_flags_all (GstAllocTraceFlags flags);
Enable the specified options on all registered alloc trace objects.
flags : |
the options to enable |
GstAllocTrace* gst_alloc_trace_get (const gchar *name);
Get the named alloc trace object.
name : |
the name of the alloc trace object |
Returns : | a GstAllocTrace with the given name or NULL when no alloc tracer was registered with that name. |
void gst_alloc_trace_print (const GstAllocTrace *trace);
Print the status of the given GstAllocTrace.
trace : |
the GstAllocTrace to print |
void gst_alloc_trace_print_live (void);
Print the status of all registered alloc trace objects, ignoring those without live objects.
void gst_alloc_trace_set_flags (GstAllocTrace *trace, GstAllocTraceFlags flags);
Enable the given features on the given GstAllocTrace object.
trace : |
the GstAllocTrace |
flags : |
flags to set |
#define gst_alloc_trace_register(name)
Register a new alloc tracer with the given name
name : |
The name of the tracer object |
#define gst_alloc_trace_new(trace, mem)
Use the tracer to trace a new memory allocation
trace : |
The tracer to use |
mem : |
The memory allocated |
#define gst_alloc_trace_free(trace, mem)
Trace a memory free operation
trace : |
The tracer to use |
mem : |
The memory that is freed |
