function

memcmp

memcmp(s1: DTypePointer[type, address_space], s2: DTypePointer[type, address_space], count: Int) -> Int

Compares two buffers. Both strings are assumed to be of the same length.

Args:

  • ​s1 (DTypePointer[type, address_space]): The first buffer address.
  • ​s2 (DTypePointer[type, address_space]): The second buffer address.
  • ​count (Int): The number of elements in the buffers.

Returns:

Returns 0 if the bytes buffers are identical, 1 if s1 > s2, and -1 if s1 < s2. The comparison is performed by the first different byte in the buffer.

memcmp[type: AnyRegType, address_space: AddressSpace](s1: LegacyPointer[type, address_space], s2: LegacyPointer[type, address_space], count: Int) -> Int

Compares two buffers. Both strings are assumed to be of the same length.

Parameters:

  • ​type (AnyRegType): The element type.
  • ​address_space (AddressSpace): The address space of the pointer.

Args:

  • ​s1 (LegacyPointer[type, address_space]): The first buffer address.
  • ​s2 (LegacyPointer[type, address_space]): The second buffer address.
  • ​count (Int): The number of elements in the buffers.

Returns:

Returns 0 if the bytes strings are identical, 1 if s1 > s2, and -1 if s1 < s2. The comparison is performed by the first different byte in the byte strings.
