trace.h - tracing
SYNOPSIS
#include <trace.h>
DESCRIPTION
The <trace.h> header shall define the posix_trace_event_info structure that includes at
least the following members:
trace_event_id_t posix_event_id
pid_t posix_pid
void *posix_prog_address
int posix_truncation_status
struct timespec posix_timestamp
pthread_t posix_thread_id
The <trace.h> header shall define the posix_trace_status_info structure that includes at
least the following members:
int posix_stream_status

int posix_stream_overrun_status
int posix_stream_flush_status
int posix_stream_flush_error
int posix_log_overrun_status
int posix_log_full_status

POSIX_TRACE_TRUNCATED_READ
POSIX_TRACE_TRUNCATED_RECORD
POSIX_TRACE_UNNAMED_USER_EVENT
POSIX_TRACE_UNTIL_FULL
POSIX_TRACE_WOPID_EVENTS
The following types shall be defined as described in <sys/types.h> :
trace_attr_t
trace_id_t
trace_event_id_t
trace_event_set_t
