copyline.c

C和指针非常好的一本书.里面的有许多代码可以借鉴.

/*
** Copy the standard input to the standard output, line by line.
*/
#include <stdio.h>

#define	MAX_LINE_LENGTH		1024	/* longest line I can copy */

void
copylines( FILE *input, FILE *output )
{
	char	buffer[MAX_LINE_LENGTH];

	while( fgets( buffer, MAX_LINE_LENGTH, input ) != NULL )
		fputs( buffer, output );
}
