NAME

       pmsprintf - formatted string conversion

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmsprintf(char *str, size_t size, const char *fmt, ... /*args*/);

       cc ... -lpcp

DESCRIPTION

       Safe string formatting interface that wraps the vsnprintf(3) call.

       It differs primarily in that pmsprintf guarantees that the output buffer str will be null-
       terminated even when the provided buffer size is insufficient  to  contain  the  formatted
       string.  In this case a null-terminated truncated string will be returned in str.

       In  the  case  of a failure in the underlying vsnprintf interface, a null-terminated empty
       string will be returned in str, and the return value will be zero.

DIAGNOSTICS

       On successful completion, pmsprintf returns  the  number  of  characters  written  to  the
       supplied buffer, not including the null terminator.

       The return code is always zero or more, never negative.
