Since P1003.1 does not define a maximum length for a path, no application
should assume that there is one. You'll have to use something more
flexible than a compile time constant.

Here is an example with getcwd() :

#define PATHSIZE 1024

char *cwdname(void)
{
        int     size = PATHSIZE;
        char *  name;

        while(1)
        {       name = (char *) malloc(size);
                if( name = NULL )
                        FatalError("out of memory");
                if( getcwd(name, size-1) != NULL )
                        return name;
                if( errno != ERANGE )
                        FatalError("getcwd() failed");
                free(name);
                size += PATHSIZE;
        }
}
