serialio's Introduction

serialio

serial port library for win & linux, in C.

SIO_ERR_NOT_OPENED

/* data bit */
SIO_EDATA_5
SIO_EDATA_6
SIO_EDATA_7
SIO_EDATA_8

/* parity */
SIO_EPAR_NONE
SIO_EPAR_ODD
SIO_EPAR_EVEN

/* stop bit */
SIO_ESTOP_1
SIO_ESTOP_1_5
SIO_ESTOP_2

/* flow control */
SIO_EFLOW_NONE
SIO_EFLOW_HARD
SIO_EFLOW_SOFT               soft flow control current not support

/* for specified bit */
SIO_EBIT_CTS
SIO_EBIT_DSR
SIO_EBIT_DTR
SIO_EBIT_RTS

functions:

/* baudrate specified in int value, like 300, 1200 and so on */
void SIO_setArg(SIO_arg_t* arg, int baudrate, SIOenum dataBit, SIOenum parType, SIOenum stopBit, SIOenum flowType);


SIO_t* SIO_create();
void SIO_release(SIO_t* io);

/* return 0 success, negative is an error code */
SIOenum SIO_open(SIO_t* io, const char* port, const SIO_arg_t* arg);
SIOenum SIO_close(SIO_t* io);

/* return actual perform count, if negative, then it is an error code */
int SIO_read(SIO_t* io, uint8_t* buf, int size);
int SIO_write(SIO_t* io, const uint8_t* buf, int size);

/* specified bit test & set & reset */
SIOenum SIO_isSetBit(SIO_t* io, SIOenum bit, SIObool* value);
SIOenum SIO_setBit(SIO_t* io, SIOenum bit);
SIOenum SIO_resetBit(SIO_t* io, SIOenum bit);
