NAME

6       pmsprintf - formatted string conversion
7

C SYNOPSIS

9       #include <pcp/pmapi.h>
10
11       int pmsprintf(char *str, size_t size, const char *fmt, ... /*args*/);

DESCRIPTION

16       Safe string formatting interface that wraps the vsnprintf(3) call.
17
18       It  differs primarily in that pmsprintf guarantees that the output buf‐
19       fer str will be null-terminated even when the provided buffer  size  is
20       insufficient to contain the formatted string.  In this case a null-ter‐
21       minated truncated string will be returned in str.
22
23       In the case of a failure in the underlying vsnprintf interface, a null-
24       terminated  empty  string will be returned in str, and the return value
25       will be zero.
26

DIAGNOSTICS

28       On successful completion, pmsprintf returns the  number  of  characters
29       written to the supplied buffer, not including the null terminator.
30
31       The return code is always zero or more, never negative.
