You'll need to use the va_copy macro and use the variants of printf that are prefixed with a "v" (e.g. vsnprintf).
See https://en.cppreference.com/w/c/io/vfprintf#Example for an example.
Thanks works a treat added the following function
Code:
void gprintf(const char *fmt, ...){ va_list args1; va_start(args1, fmt); va_list args2; va_copy(args2, args1); char buf[1+vsnprintf(NULL, 0, fmt, args1)]; va_end(args1); vsnprintf(buf, sizeof buf, fmt, args2); va_end(args2); printf("%s",buf); fprintf(file,"%s",buf);}Code:
gprintf("\n Data %s next data %s ",data[3] [0],data[3] [1]); // access datagprintf("\n Data %s - \n",data[0] [0]); // access dataStatistics: Posted by Geralds — Mon Feb 05, 2024 8:00 pm
