setbuf - assign buffering to a stream
Návod, kniha: POSIX Programmer's Manual
#include <stdio.h>
void setbuf(FILE *restrict
stream, char
*restrict buf);
Except that it returns no value, the function call:
shall be equivalent to:
setvbuf(stream, buf, _IOFBF, BUFSIZ)
if
buf is not a null pointer, or to:
setvbuf(stream, buf, _IONBF, BUFSIZ)
if
buf is a null pointer.
The
setbuf() function shall not return a value.
No errors are defined.
The following sections are informative.
None.
A common source of error is allocating buffer space as an "automatic"
variable in a code block, and then failing to close the stream in the same
block.
With
setbuf(), allocating a buffer of BUFSIZ bytes does not necessarily
imply that all of BUFSIZ bytes are used for the buffer area.
None.
