This retrieves the MD5 hash of the file.
It corresponds to the [HashID] column of the [File] table.
Contents
Syntax
void truxton_file_get_hash( uint64_t file_handle, uint64_t which_hash, char * destination_string, size_t max_size );
Parameters
file_handle
The handle created by the truxton_file_open_id or truxton_file_open_md5 call.
which_hash
Which hash to get. 0 is MD5, 1 is SHA1.
destination_string
The string to be written to.
max_size
The maximum number of characters that can be written to destination_string.
Sample
void print_id( uint64_t truxton )
{
uint64_t file = truxton_file_open_md5( truxton, "9ec8fb6095c35eff2b236863b7caaf10" );
if ( file != 0 )
{
return;
}
char hash_string[ MAX_PATH ];
truxton_file_get_hash( file, 0, hash_string, sizeof(hash_string) );
printf( "Hash is %s\n", hash_string );
truxton_file_free( file );
}
