Rewind (C)
From Wikipedia, the free encyclopedia
- The correct title of this article is rewind (C). The initial letter is shown capitalized due to technical restrictions.
rewind is part of stdio.h in the C standard library. It sets the file pointer associated with the stream to the beginning of the file.
Prototype:
void rewind ( FILE * stream );
A call to rewind is equivalent to:
fseek ( stream , 0L , SEEK_SET );
except that unlike fseek, using rewind the error indicator is cleared.
The next operation with the stream after a call to fseek can be either for input or output. This function is also useful for clearing the keyboard buffer (normally associated with stdin).
