This retrieves the filesystem attributes of the file.
It corresponds to the Attributes column of the File table.
Syntax
uint32_t truxton_file_get_attributes( uint64_t file_handle );
Parameters
file_handle
The handle created by the truxton_file_open_id or truxton_file_open_md5 call.
Return value
The attributes of the file. For a Microsoft filesystem, it will return a combination of the file attribute flags.
Sample
int print_it(uint64_t truxton)
{
uint64_t file = truxton_file_open_md5(truxton, "9ec8fb6095c35eff2b236863b7caaf10");
if ( file != 0 )
{
return(0);
}
uint32_t attributes = truxton_file_get_attributes( file );
printf( "Attributes are %" PRIu32 "\n", attributes );
}
Note, the PRIu32 in the sample code above is the new standard way of formatting a 32-bit integer in C.
Over the years, different compilers on different operating systems used different format specifiers for things, these PRI macros, along with some tricky string concatenation the compilers perform for you, allow you to maintain a single code base without a bunch of macro magic.
