Thread: Read more than one line in a file

If you want to read the whole file, just use fread():

Code:

#include <stdio.h>
#include <malloc.h>

int main()
{
	long length;
	char* buf;
	size_t bytes;
	FILE* file = fopen( "c:/file.txt", "rb" );

	if ( file == NULL )
	{
		printf( "Error opening file!" );
		return 1;
	}

	if ( fseek( file, 0, SEEK_END ) != 0 )
	{
		fclose( file );
		printf( "fseek() failed!" );
		return 2;
	}

	if ( (length = ftell( file )) < 0 )
	{
		fclose( file );
		printf( "ftell() failed!" );
		return 3;
	}

	if ( fseek( file, 0, SEEK_SET ) != 0 )
	{
		fclose( file );
		printf( "fseek() failed!" );
		return 2;
	}

	if ( (buf = malloc( length + 1 )) == NULL )
	{
		fclose( file );
		printf( "malloc() failed!" );
		return 4;
	}

	if ( (bytes = fread( buf, 1, length, file )) != (size_t)length )
	{
		free( buf );
		fclose( file );
		printf( "fread() didn't read &#37;d bytes!", length );
		return 5;
	}

	fclose( file );
	buf[length] = '\0';
	printf( "Text file contents:\n%s", buf );
	free( buf );

	return 0;
}
