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.
