* Name: setbuf
|
|
*
|
|
* Description:
|
|
* 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.
|
|
*
|
|
* Input Parameters:
|
|
* stream - The stream whose buffer will be modified
|
|
* buffer - If non-NULL, this is user allocated buffer of size BUFSIZ. If
|
|
* NULL, setvbuf will disable buffering
|
|
*
|
|
* Returned Value:
|
|
* None
