+FUNCTION
+<<fread>>---read array elements from a file
+
+INDEX
+	fread
+
+ANSI_SYNOPSIS
+	#include <stdio.h>
+	size_t fread(void *<[buf]>, size_t <[size]>, size_t <[count]>,
+		     FILE *<[fp]>);
+
+TRAD_SYNOPSIS
+	#include <stdio.h>
+	size_t fread(<[buf]>, <[size]>, <[count]>, <[fp]>)
+	char *<[buf]>;
+	size_t <[size]>;
+	size_t <[count]>;
+	FILE *<[fp]>;
+
+DESCRIPTION
+<<fread>> 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 @emph{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>>.

+/**
+Read block of data from a stream.
+Read count number of items each one with a size of size bytes from the stream
+and stores it in the specified buffer.
+Stream's postion indicator is increased by the number of bytes readed.
+Total amount of bytes read is (size x count).
+@return   The total number of items readed is returned.
+@param buf Pointer to the destination structure with a minimum size of (size*count) bytes. 
+@param size Size in bytes of each item to be read. 
+@param count Number of items, each one with a size of size bytes. 
+@param fp pointer to an open file.
