Синопсис C (C Synopsis)

Описание (Description)
For use in error and diagnostic messages, pmEventFlagsStr
returns
a `human readable' version of the value flags, assuming this to
be the er_flags
field of a pmEventRecord
or pmEventHighResRecord
.
The pmEventFlagsStr_r
function does the same, but stores the
result in a user-supplied buffer buf of length buflen, which
should have room for at least 64 bytes.
The string value result from pmEventFlagsStr
is held in a single
static buffer, so the returned value is only valid until the next
call to pmEventFlagsStr
.
Примечание (Note)
pmEventFlagsStr
returns a pointer to a static buffer and hence is
not thread-safe. Multi-threaded applications should use
pmEventFlagsStr_r
instead.
