NAME         top

       pmstrncpy - safe string copy

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       int pmstrncpy(char *dest, size_t destlen, char *src);

       cc ... -lpcp

DESCRIPTION         top

       pmstrncpy is safe string copying routine with semantics similar
       to strncpy(3).

       The main differences are that src must be null-byte terminated,
       destlen is the length of the destination buffer (dest) not the
       length of the source string (src), and pmstrncpy ensures that
       dest is null-byte terminated, even when strlen(src) is larger
       than destlen.

       On success, pmstrncpy returns 0, else -1 indicates that src is
       too big and the result been truncated to ensure dest has no been
       overrun.
