fwrite
Description:

Arguments:
Return Value:
Remarks:
Example:
Writes data to the stream.
<stdio.h>
size_t fwrite(const void *ptr, size_t size,
ptr
size
nelem
stream
Returns the number of complete elements successfully written, which
will be less than nelem only if a write error is encountered.
The function writes characters to a given stream from a buffer pointed
to by ptr up to nelem elements whose size is specified by size. The
file position indicator is advanced by the number of characters success-
fully written. If the function sets the error indicator, the file-position indi-
cator is indeterminate.
#include <stdio.h> /* for fread, fwrite,

}
numwrote = fwrite(nums, sizeof(double),
printf("Wrote %d numbers\n\n", numwrote);
fclose(buf);
