modbus_write_bits(3) ==================== NAME ---- modbus_write_bits - write many bits SYNOPSIS -------- *int modbus_write_bits(modbus_t *'ctx', int 'addr', int 'nb', const uint8_t *'src');* DESCRIPTION ----------- The *modbus_write_bits()* function shall write the status of the _nb_ bits (coils) from _src_ at the address _addr_ of the remote device. The _src_ array must contains bytes set to `TRUE` or `FALSE`. The function uses the Modbus function code 0x0F (force multiple coils). RETURN VALUE ------------ The function shall return the number of written bits if successful. Otherwise it shall return -1 and set errno. ERRORS ------ *EMBMDATA*:: Writing too many bits SEE ALSO -------- linkmb:modbus_read_bits[3] linkmb:modbus_write_bit[3] AUTHORS ------- The libmodbus documentation was written by Stéphane Raimbault
