Имя (Name)
pmEventFlagsStr, pmEventFlagsStr_r - convert an event record
flags value into a string
Синопсис C (C Synopsis)
#include <pcp/pmapi.h>
const char *pmEventFlagsStr(int flags);
char *pmEventFlagsStr_r(int flags, char *buf, int buflen);
cc ... -lpcp
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.
