+ * void* '''memcpy'''( void* dst, const void* src, unsigned int size )
 This function copies ''size'' bytes from the ''src'' source buffer to the ''dst'' destination buffer.
 
- * '''void* memset( void* dst, int s, unsigned int size )'''
+ * void* '''memset'''( void* dst , int s , unsigned int size )
 This function initializes ''size'' bytes in the ''dst'' destination buffer, with the value defined by ''(char)s''.
+
+ * unsigned int '''strlen'''( char* string )
+This function returns the number of characters in a string. The terminating NUL character is not taken into account.
