macro 'NUMSHADES' defines an integral constant; prefer an enum instead

variable 'color_shades' is non-const and globally accessible, consider making it const

macro argument should be enclosed in parentheses

variable 'stopped' is non-const and globally accessible, consider making it const

Call to function 'memcpy' is insecure as it does not provide security checks introduced in the C11 standard. Replace with analogous functions that support length arguments or provides boundary checks such as 'memcpy_s' in case of C11

result of multiplication in type 'int' is used as a pointer offset after an implicit widening conversion to type 'ptrdiff_t'

statement should be inside braces

statement should be inside braces

multiple declarations in a single statement reduces readability

variable 'ErrorAccTemp' is not initialized
