Unsigned Byte

An xsd:unsignedByte is an unsigned 8-bit integer.

Values range from 0 to 255 inclusive.

The lexical form is the same as xsd:unsignedLong, the only difference is that the value space of xsd:unsignedByte is smaller. See Unsigned Long for details.

ExessResult exess_read_ubyte(uint8_t *out, const char *str)

Read an xsd:unsignedByte string after any leading whitespace.

Parameters

• out – Set to the parsed value, or zero on error.

• str – String input.

Returns

The count of characters read, and a status code.

ExessResult exess_write_ubyte(uint8_t value, size_t buf_size, char *buf)

Write a canonical xsd:unsignedByte string.

Parameters

• value – Value to write.

• buf_size – The size of buf in bytes.

• buf – Output buffer, or null to only measure.

Returns

The count of characters in the output, and status ExessStatus.EXESS_SUCCESS, or ExessStatus.EXESS_NO_SPACE if the buffer is too small.

EXESS_MAX_UBYTE_LENGTH

The maximum length of a canonical xsd:unsignedByte string, 3.
