C <stdio.h> - BUFSIZ constant
The C <stdio.h> BUFSIZ is a macro constant that expands to an integral expression with the size of the buffer used by the setbuf() function.
In the <stdio.h> header file, it is defined as follows:
#define BUFSIZ /* implementation defined */
Example:
The example below shows the value of BUFSIZ constant in a given implementation.
#include <stdio.h>
int main (){
//displaying the value of BUFSIZ
printf("BUFSIZ = %d\n", BUFSIZ);
return 0;
}
The output of the above code will be:
BUFSIZ = 8192
