trusty (3) pmEventFlagsStr_r.3.gz

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.  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.
