This type is used library-wide for passing error codes in the return value of functions. 
 
struct brp_protocol_t * brp_protocol
This is a generic handle of a protocol. 
 
brp_errcode brp_Ultralight_Write(brp_protocol protocol, unsigned PageAdr, brp_buf PageData)
Standard write command for Ultralight cards. 
 
brp_Ultralight_AuthE2_DivMode
