This tells you if the file handle has been closed. If it has, you can no longer read bytes from it.
Syntax
int truxton_file_is_closed( uint64_t file_handle );
Parameters
file_handle
The handle created by the truxton_file_open_id or truxton_file_open_md5 call.
Return value
If file contents are not available, the return value will be 1, otherwise it will be zero.
Sample
void test_close( uint64_t truxton )
{
uint64_t file = truxton_file_open_id( truxton, "5ed3aeb7-3da4-5f5c-8c8f-af5200000000" );
if ( file != 0 )
{
return;
}
truxton_file_close( file );
if ( truxton_file_is_closed( file ) == 0 )
{
printf( "Truxton file is broken. Can't close file.\n" );
}
truxton_file_free( file );
}
