Available on crate feature dep_sdl3 only.
Expand description

Parse an unsigned long long from a string.

If str starts with whitespace, then those whitespace characters are skipped before attempting to parse the number.

If the parsed number does not fit inside an unsigned long long, the result is clamped to the maximum representable unsigned long long value.

§Parameters

  • str: The null-terminated string to read. Must not be NULL.
  • endp: If not NULL, the address of the first invalid character (i.e. the next character after the parsed number) will be written to this pointer.
  • base: The base of the integer to read. Supported values are 0 and 2 to 36 inclusive. If 0, the base will be inferred from the number’s prefix (0x for hexadecimal, 0 for octal, decimal otherwise).

§Return value

Returns the parsed unsigned long long, or 0 if no number could be parsed.

§Thread safety

It is safe to call this function from any thread.

§Availability

This function is available since SDL 3.2.0.
