Hmm...that's a bug.
Fixed in svn revision #940 for the 1.1 branch and #941 for the 1.0 branch.
This program now works as you'd expect with that fix (although note that
if file.txt is empty, it'll write two '\0' chars to the start, since
we're seeking past the end of file. I don't think PhysicsFS makes any
guarantees on that behaviour at the moment).
#include <stdio.h>
#include "physfs.h"
int main(int argc, char **argv)
{
PHYSFS_init(argv[0]);
PHYSFS_setWriteDir(".");
char string[]="TEST";
PHYSFS_file *file = PHYSFS_openAppend("file.txt");
printf("tell == %d\n",(int) PHYSFS_tell(file));
printf("seek 2 == %d\n", (int) PHYSFS_seek(file, 2));
printf("tell == %d\n",(int) PHYSFS_tell(file));
printf("write 4 == %d\n", (int) PHYSFS_write(file, string, 1, 4));
printf("tell == %d\n", (int) PHYSFS_tell(file));
PHYSFS_close(file);
return 0;
}
