setbuf
Description:

Arguments:
Remarks:
Example:
Defines how a stream is buffered.
<stdio.h>
void setbuf(FILE *stream, char *buf);
stream
buf
setbuf must be called after fopen but before any other function calls
that operate on the stream. If buf is a null pointer, setbuf calls the
function setvbuf(stream, 0, _IONBF, BUFSIZ) for no buffering;
otherwise setbuf calls setvbuf(stream, buf, _IOFBF, BUF-
SIZ) for full buffering with a buffer of size BUFSIZ. See setvbuf.
#include <stdio.h> /* for setbuf, printf, */
int main(void)
{
}
Output:
myfile1 has no buffering
myfile2 has full buffering
FILE *myfile1, *myfile2;
char buf[BUFSIZ];
if ((myfile1 = fopen("afile1", "w+")) != NULL)
{
}
if ((myfile2 = fopen("afile2", "w+")) != NULL)
{
}
setbuf(myfile1, NULL);
printf("myfile1 has no buffering\n");
fclose(myfile1);
setbuf(myfile2, buf);
printf("myfile2 has full buffering");
fclose(myfile2);
