Websetbuf is defined as follows: void setbuf (FILE *stream, char *buf); Except that it returns no value, the function call: setbuf (stream, buf) is 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 return value from setbuf is

Web22 Jun 2024 · We can unbuffer the output using setbuf from stdio.h. The prototype of setbuf is extern void setbuf (FILE *__restrict __stream, char *__restrict __buf) __THROW; It takes in a FILE pointer as the first parameter. We can supply stdout as the first parameter, this word is defined under stdio.h. WebThe buffering mode of the standard streams (or any other stream) can be changed using the setbuf (3) or setvbuf (3) call. Note that in case stdin is associated with a terminal, there may also be input buffering in the terminal driver, entirely unrelated to stdio buffering. (Indeed, normally terminal input is line buffered in the kernel.)

Websetbuf controls buffering for the specified stream on operating systems that support user-defined buffers. setbuf is similar to the setvbuf function. If buf is not NULL , then the values _IOFBF and BUFSIZE are used for setvbuf 's mode and size arguments. If buf is NULL , then the value _IONBF is used for setvbuf 's mode argument. Websetbuf is defined in header stdio.h . In short, the setbuf does assign buffering to a stream. setbuf is defined as follows: void setbuf (FILE *stream, char *buf); Except that it returns …
