POSIX_TRACE_ATTR_GETCLOCKRES(P) POSIX_TRACE_ATTR_GETCLOCKRES(P)
NAME
posix_trace_attr_getclockres, posix_trace_attr_getcreatetime, posix_trace_attr_get-
genversion, posix_trace_attr_getname, posix_trace_attr_setname - retrieve and set
information about a trace stream (TRACING)
SYNOPSIS
#include <time.h>
#include <trace.h>
int posix_trace_attr_getclockres(const trace_attr_t *attr,
struct timespec *resolution);
int posix_trace_attr_getcreatetime(const trace_attr_t *attr,
struct timespec *createtime);
#include <trace.h>
int posix_trace_attr_getgenversion(const trace_attr_t *attr,
char *genversion);
int posix_trace_attr_getname(const trace_attr_t *attr,
char *tracename);
int posix_trace_attr_setname(trace_attr_t *attr,
const char *tracename);
DESCRIPTION
The posix_trace_attr_getclockres() function shall copy the clock resolution of the
clock used to generate timestamps from the clock-resolution attribute of the
attributes object pointed to by the attr argument into the structure pointed to by
the resolution argument.
The posix_trace_attr_getcreatetime() function shall copy the trace stream creation
time from the creation-time attribute of the attributes object pointed to by the
attr argument into the structure pointed to by the createtime argument. The cre-
ation-time attribute shall represent the time of creation of the trace stream.
The posix_trace_attr_getgenversion() function shall copy the string containing ver-
sion information from the generation-version attribute of the attributes object
pointed to by the attr argument into the string pointed to by the genversion argu-
ment. The genversion argument shall be the address of a character array which can
store at least {TRACE_NAME_MAX} characters.
The posix_trace_attr_getname() function shall copy the string containing the trace
name from the trace-name attribute of the attributes object pointed to by the attr
argument into the string pointed to by the tracename argument. The tracename argu-
ment shall be the address of a character array which can store at least
{TRACE_NAME_MAX} characters.
The posix_trace_attr_setname() function shall set the name in the trace-name
attribute of the attributes object pointed to by the attr argument, using the trace
name string supplied by the tracename argument. If the supplied string contains
more than {TRACE_NAME_MAX} characters, the name copied into the trace-name
attribute may be truncated to one less than the length of {TRACE_NAME_MAX} charac-
ters. The default value is a null string.
RETURN VALUE
Upon successful completion, these functions shall return a value of zero. Other-
wise, they shall return the corresponding error number.
If successful, the posix_trace_attr_getclockres() function stores the clock-resolu-
tion attribute value in the object pointed to by resolution. Otherwise, the content
of this object is unspecified.
If successful, the posix_trace_attr_getcreatetime() function stores the trace
stream creation time in the object pointed to by createtime. Otherwise, the content
of this object is unspecified.
If successful, the posix_trace_attr_getgenversion() function stores the trace ver-
sion information in the string pointed to by genversion. Otherwise, the content of
this string is unspecified.
If successful, the posix_trace_attr_getname() function stores the trace name in the
string pointed to by tracename. Otherwise, the content of this string is unspeci-
fied.
ERRORS
The posix_trace_attr_getclockres(), posix_trace_attr_getcreatetime(),
posix_trace_attr_getgenversion(), and posix_trace_attr_getname() functions may fail
if:
EINVAL The value specified by one of the arguments is invalid.
