Имя (Name)
pmTypeStr, pmTypeStr_r - convert a performance metric type into a
string
Синопсис C (C Synopsis)
#include <pcp/pmapi.h>
const char *pmTypeStr(int type);
char *pmTypeStr_r(int type, char *buf, int buflen);
cc ... -lpcp
Описание (Description)
Given a performance metric type, pmTypeStr produces a terse ASCII
equivalent, appropriate for use in error and diagnostic messages.
The pmTypeStr_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 20 bytes.
The value for type is typically extracted from a pmDesc
structure, following a call to pmLookupDesc(3) for a particular
performance metric.
Examples are 32 (for type equals PM_TYPE_32), U64 (for type
equals PM_TYPE_U64), STRING (for type equals PM_TYPE_STRING),
etc.
Примечание (Note)
Both of these functions are safe to call from threaded contexts.
