POSIX_TRACE_ATTR_GETCLOCKRES(P)     POSIX Programmer's Manual	  POSIX_TRACE_ATTR_GETCLOCKRES(P)

NAME
       posix_trace_attr_getclockres,  posix_trace_attr_getcreatetime, posix_trace_attr_getgenver-
       sion, 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 creation-time attribute
       shall represent the time of creation of the trace stream.

       The posix_trace_attr_getgenversion() function shall copy  the  string  containing  version
       information  from  the generation-version attribute of the attributes object pointed to by
       the attr argument into the string pointed to by the genversion  argument.  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 argument 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  sup-
       plied   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  trun-
       cated  to  one less than the length of {TRACE_NAME_MAX} characters. The default value is a
       null string.

RETURN VALUE
       Upon successful completion, these functions shall return a value of zero. Otherwise,  they
       shall return the corresponding error number.

       If  successful,	the  posix_trace_attr_getclockres()  function stores the clock-resolution
       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 cre-
       ation 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 version
       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 unspecified.

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.
