Re: Is this kosher?

Folks,

My thanks to one and all!
Now I'm a little wiser.

Best regards,

Folks,

I just wrote a little function to find the end of a line:

char *eol(char *pt)
{ while(*pt != '\r' && *pt != '\n' && *pt != '\0') // run along to the
line terminator character
pt++;
return pt; // and return a pointer to it
}

I use it thus:

main() // I know, I know!
{ char text_line[260], *t_pt;

/* [ get a file path into text_line] */

t_pt = eol(text_line);
*t_pt = '\0'; // this knocks off a '\n', which stops chdir() from
working

chdir(text_line);
}

This works fine, but just for the experiment, I replaced the two lines
containing t_pt with

*eol(text_line) = '\0';

... and it worked. Is this a syntactical thing to do? Is it portable?
I'd appreciate your educated comment on this.

Thanks a heap,

MikeC.
