pmEventFlagsStr, pmEventFlagsStr_r - convert an event record flags value into a string
Contents
C Synopsis
#include<pcp/pmapi.h>constchar*pmEventFlagsStr(intflags);char*pmEventFlagsStr_r(intflags,char*buf,intbuflen);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 pmHighResEventRecord. 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.
Name
pmEventFlagsStr, pmEventFlagsStr_r - convert an event record flags value into a string
Notes
pmEventFlagsStr returns a pointer to a static buffer and hence is not thread-safe. Multi-threaded
applications should use pmEventFlagsStr_r instead.
