This retrieves the URL that was visited.
Syntax
void truxton_url_get_url( uint64_t url_handle, char * destination_string, size_t max_size );
Parameters
url_handle
This handle comes from calling truxton_url_create(), or truxton_file_create_url().
destination_string
The string to be written to.
max_size
The maximum number of characters that can be written to destination_string.
Sample
void dump_url(uint64_t url_handle)
{
uint64_t integer_value = 0;
char temp_string[ 1024 ];
truxton_url_get_id( url_handle, temp_string, sizeof(temp_string) );
printf( "URL ID is %s\n", temp_string );
truxton_url_get_media_id( url_handle, temp_string, sizeof(temp_string) );
printf( "Media ID is %s\n", temp_string );
truxton_url_get_file_id( url_handle, temp_string, sizeof(temp_string) );
printf( "File ID is %s\n", temp_string );
truxton_url_get_account( url_handle, temp_string, sizeof(temp_string) );
printf( "Account is \"%s\"\n", temp_string );
integer_value = truxton_url_get_account_offset( url_handle );
if ( integer_value == 0xFFFFFFFFFFFFFFFF )
{
printf( "Account offset is not known\n" );
}
else
{
printf( "Account offset is %" PRIu64 "\n", integer_value );
}
integer_value = truxton_url_get_url_offset( url_handle );
if ( integer_value == 0xFFFFFFFFFFFFFFFF )
{
printf( "URL offset is not known, probably came from a SQLite database\n" );
}
else
{
printf( "URL offset is %" PRIu64 "\n", integer_value );
}
integer_value = truxton_url_get_format( url_handle );
printf( "Format is %" PRIu64 "\n", integer_value );
integer_value = truxton_url_get_method( url_handle );
printf( "Method is %" PRIu64 "\n", integer_value );
integer_value = truxton_url_get_type( url_handle );
printf( "Type is %" PRIu64 "\n", integer_value );
integer_value = truxton_url_get_when( url_handle );
printf( "When is %" PRIu64 "\n", integer_value );
truxton_url_get_url( url_handle, temp_string, sizeof(temp_string) );
printf( "URL is \"%s\"\n", temp_string);
}
The PRIu64 in the sample code above is a standard way of formatting a 64-bit unsigned 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.
