CMP_SIG

Compare float.

• Param v1: A float to compare
• Param v2: Another float to compare

CMP_SIG(float);

CMP_SIG

Compare strings.

• Param v1: A string to compare
• Param v2: Another string to compare

CMP_SIG(str);

CMP_SIG

Compare ints.

• Param v1: An int to compare
• Param v2: Another int to compare

CMP_SIG(int);

CMP_SIG

Compare size_ts.

• Param v1: A size_t to compare
• Param v2: Another size_t to compare

CMP_SIG(size_t);

CMP_SIG

Compare doubles.

• Param v1: A double to compare
• Param v2: Another double to compare

CMP_SIG(double);

CMP_SIG

The signature of a comparator.

• Param name: The name of the comparison functino

Returns: The signature of the comparison function for names

#	define CMP_SIG(name) Cmp cmp_##name##s(void* v1, void* v2)

CMP_SIG

Compare characters.

• Param v1: A character to compare
• Param v2: Another character to compare

CMP_SIG(char);

CMP_SIG

Compare void pointer. This compares the numerical value of the pointers, not their content!

• Param v1: A void pointer to compare
• Param v2: Another void pointer to compare

CMP_SIG(ptr);

Cmp

Type of a function which compares two values.

• Param v1: A value to compare
• Param v2: Another value to compare

Returns: The comparison result of v1 against v2

typedef Cmp(fun Comparator)(void* v1, void* v2);

streq

Check if two C-strings are equal (to improve readability with strcmp).

• Param s: Pointer to a string to check
• Param t: Pointer to a string to check

Returns: true if the strings are equal, false otherwise

bool streq(char const* s, char const* t);
