[Bf-committers] unixNewLine and winNewLine

[Alexander Ewering]

Hi theeth and the rest,

uhm, just stumbled over the unixNewLine and winNewLine
functions accidentally, and figured they could need some
cleanup... Here are my versions (they are quite a bit
faster, too):

char *unixNewLine(char *buffer)
{
	char *p, *p2, *output;
	
	/* we can afford the few extra bytes */
	output= MEM_callocN(strlen(buffer)+1, "unixnewline");
	for (p= buffer, p2= output; *p; p++)
		if (*p != '\r') *(p2++)= *p;
	
	*p2= 0;
	return(output);
}

char *winNewLine(char *buffer)
{
	char *p, *p2, *output;
	int add= 0;
	
	for (p= buffer; *p; p++)
		if (*p == '\n') add++;
		
	bufferlength= p-buffer+add+1;
	output= MEM_callocN(bufferlength, "winnewline");
	for (p= buffer, p2= output; *p; p++, p2++) {
		if (*p == '\n') { 
			*(p2++)= '\r'; *p2= '\n';
		} else *p2= *p;
	}
	*p2= 0;
	
	return(output);
}
