PMSTRNCAT(3)            Library Functions Manual            PMSTRNCAT(3)

NAME         top

       pmstrncat - safe string concatenation

C SYNOPSIS         top

       #include <pcp/pmapi.h>

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

       cc ... -lpcp

DESCRIPTION         top

       pmstrncat is safe string concatenation routine with semantics
       similar to strncat(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 pmstrncat ensures that
       dest is null-byte terminated, even when strlen(src) is larger
       than the remaining space in dest (destlen - strlen(dest) on
       entry).

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