NAME¶
pmEventFlagsStr,
pmEventFlagsStr_r - convert an event record flags
value into a string
C SYNOPSIS¶
#include <pcp/pmapi.h>
const char *pmEventFlagsStr(int
flags);
char *pmEventFlagsStr_r(int
flags, char *
buf, int
buflen);
cc ... -lpcp
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.
NOTES¶
pmEventFlagsStr returns a pointer to a static buffer and hence is not
thread-safe. Multi-threaded applications should use
pmEventFlagsStr_r
instead.
