Info

TMS34010 C Language - Identifiers, Keywords, and Constants it treats them as ordinary doubles. The L suffix is supported to provide compatibility with ANSI C. Examples of floating-point constants include: 1.234; /* double */ 1.0e14F; /* float */ 3.14159L; /* double */ Suffixes can be upper or lower case. Added type - Enumeration Constants An enumeration constant is an additional type of integer constant that is not described by K&R. An identifier that is declared as an enumerator can be used in the same manner as an integer constant. (For more information about enumerators, see Section 4.6 on page 4-8.) K&R 2.5 - String Constants • K&R C does not limit the length of string constants; however, TMS34010 C limits the length of string constants to 255 bytes. • All characters after an embedded null byte in a string constant are ignored; in other words, the first null byte terminates the string. However, this does not apply to strings used to initialize arrays of characters. • Identical string constants are stored as a single string, not as separate strings as in K& R C. However, this does not apply to strings used to autoinitialize arrays of characters. 4-3
TMS34010 C Language - Data Types 4.2 TMS34010 C Data Types K&R 4.0 - Equivalent Types • The char data type is signed. A separate type, unsigned char, is supported. • long and int are functionally equivalent types. Either of these types can be declared unsigned. • double and long double are functionally equivalent types. • The properties of enum types are identical to those of unsigned int. K&R 4.0 - Additional Types • An additional type, called void, can be used to declare a function that returns no value. The compiler checks that functions declared as void do not return values and that they are not used in expressions. Functions are the only type of objects that can be declared void. . • The compiler also supports a type that is a pointer to void (void *). An object of type void * can be converted to and from a pointer to an object of any other type without explicit conversions (casts). However, such a pointer cannot be used indirectly to access the object that it points to without a conversion. For example, void *p, *malloc(); char *c; int i; p p p c i K&R 4.0 - Derived Types i malloc(); c; &i; malloc(); *p; *(int *)p; /* /* /* /* /* /* Legal */ Legal, no cast needed Legal, no cast needed Legal, no cast needed Illegal, dereferencing void pointer Legal, dereferencing casted void pointer */ */ */ TMS34010 C allows any type declaration to have up to six derived types. Constructions such as pointer to, array of, and function returning can be combined and applied a maximum of six times. For example: int (* (*n[] []) () ) (); translates as: 1 } an array of 2} arrays of 3) pointers to ·4) functions returning 5) pointers to 6) functions returning integers It has six derived types, which is the maximum allowed. */ */ 4-4
