warning: passing argument 1 of âtcflushâ makes integer from pointer without a cast [e

FILE *err_fp, *barcode_ffd;
C++ code 64 bit LINUX.

barcode_ffd = fopen(barcode_p rinter,"w");

tcflush(barcode _ffd,TCIOFLUSH) ; /* clear out buffers for printer */

THE TCFLUSH gives me the error, what code is needed to fix this...

[weaknessforcats]

barcode_ffd is a FILE*.

the tcflush argument is an int and the return is also an int.

The compiler is telling you that a FILE* is not an int.

I suspect that tcflush is not the function you want. Instead you may want the flush for a FILE*. That function is:

int fflush(FILE *stream);

so your code fix is:

fflush(barcode_ffd);
