Unsigned Long

An xsd:unsignedLong is an unsigned 64-bit integer, written in decimal.

Values range from 0 to 18446744073709551615 inclusive.

Canonical form has no leading “+” sign and no leading zeros (except for the number “0”), like “0”, and “1234”.

Non-canonical form allows any number of leading zeros, like “01” and “0001234”.

ExessResult exess_read_ulong(uint64_t *out, const char *str)

Read an xsd:unsignedLong 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_ulong(uint64_t value, size_t buf_size, char *buf)

Write a canonical xsd:unsignedLong 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_ULONG_LENGTH

The maximum length of a canonical xsd:unsignedLong string, 20.
