Currently, your best bet would be to include the physfs shared library
with your app and not concern yourself with what the user has installed.
I'm considering changing the license to something like the BSD license,
which would allow static linking.

Untested code follows:

int numFilesInDir(const char *dirName)
    char **rc = PHYSFS_enumerateFiles(dirName);
    char **i;
    int retval = 0;

    for (i = rc; *i != NULL; i++)


// This will return empty lines if you've got DOS-style "\r\n" endlines!
//  extra credit for handling buffer overflows and EOF more gracefully.
void readOneLine(PHYSFS_file *f, char *buf, int bufsize)
    int total = 0;
    bufsize--;  /* allow for null terminating char */
    while ((total < bufsize) && (PHYSFS_read(f, buf, 1, 1) == 1))
        if ((*buf == '\r') || (*buf == '\n'))

    *buf = '\0';  // null terminate it.
