getw - Read wordwise from a file

Definition	#include <stdio.h> int getw(FILE *fp); getw reads a machine word from the file with the file pointer fp and positions the read/write pointer after the word read. A machine word may be conceived of as a binary integer value.
Return val.	word read as an integer value
		if successful.
	EOF	or end of file or error.
Notes	Since word length and byte arrangement are system-dependent, it is possible that files written with putw on a non-BS2000 operating system may not be readable with getw in BS2000. Since EOF represents a valid integer value, you should use the functions feof and ferror to check for end of file or error conditions. The following applies in the case of text files with SAM access mode and variable record length for which a maximum record length is also specified: When the specification split=no was entered for fopen, records of maximum record length are not concatenated with the subsequent record when they are read. By default or with the specification split=yes, when a record with maximum record length is read, it is assumed that the following record is the continuation of this record and the records are concatenated.
Example	The following program fragment reads wordwise from the file with file pointer fp until end of file is reached. int buf[MAX]; int i = 0; FILE *fp; while(!feof(fp) && !ferror(fp)) buf[i++] = getw(fp);
