fread---read array elements from a file
#include <stdio.h>
size_t fread(void *buf, size_t size, size_t count,
FILE *fp);
Descriptionfread attempts to copy, from the file or stream identified by
fp, count elements (each of size size) into memory,
starting at buf. fread may copy fewer elements than
count if an error, or end of file, intervenes.
fread also advances the file position indicator (if any) for
fp by the number of characters actually read.
Returns
The result of fread is the number of elements it succeeded in
reading.
Portability
ANSI C requires fread.
Supporting OS subroutines required: close, fstat, isatty,
lseek, read, sbrk, write.
