C/Strncatf
From Attie's Wiki
This is a variation of strcat()
that allows you to pass a formatted string like printf()
. It also takes a max length for dest, not for how much of src to use (like strncat()
.
char *strncatf(char *dest, int length, char *format, ...) { char buf[4096]; va_list ap; va_start(ap,format); vsnprintf(buf,sizeof(buf),format,ap); va_end(ap); length -= strlen(dest); strncat(dest,buf,length-1); }
