Function anj_string_to_uint64_value

Function Documentation

int anj_string_to_uint64_value(uint64_t *out_val, const char *buff, size_t buff_len)

Parse a decimal string into uint64_t.

Note

The input string is not required to be null-terminated. The caller must explicitly provide the length in buff_len (e.g., using strlen() if the content is null-terminated).

Parameters:

  • out_val – [out] Parsed value.

  • buff – Input buffer.

  • buff_len – Input length.

Returns:

0 on success, -1 on error (empty input, non-digits present, overflow, or excessive length).
