PMEVENTFLAGSSTR(3)      Library Functions Manual      PMEVENTFLAGSSTR(3)

NAME         top

       pmEventFlagsStr, pmEventFlagsStr_r - convert an event record
       flags value into a string

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       const char *pmEventFlagsStr(int flags);
       char *pmEventFlagsStr_r(int flags, char *buf, int buflen);

       cc ... -lpcp

DESCRIPTION         top

       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.

NOTES         top

       pmEventFlagsStr returns a pointer to a static buffer and hence is
       not thread-safe.  Multi-threaded applications should use
       pmEventFlagsStr_r instead.
