PMEVENTFLAGSSTR

NAME
C SYNOPSIS
DESCRIPTION

SEE ALSO

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 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

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