C± ± Compiler

5.9.5Include Files

There are currently two include files supplied with C± ±, cmm_func.h, which contains function prototypes for the C± ±functions and cmm_macr.h which contains some predefined macros. Both files are listed below:

/********************************/

/* Prototypes for C± ±functions */

/********************************/

cmm_func add_string(int *result,int *str1,int *str2,int lg); cmm_func sub_string(int *result,int *str1,int *str2,int lg); cmm_func mul_string(int *result,int *str1,int mult,int lg1,int lgr);

cmm_func umul_string(int *result,int *str1,unsigned int mult,int lg1,int lgr); cmm_func or_string(int *result,int *str1,int *str2,int lg);

cmm_func and_string(int *result,int *str1,int *str2,int lg); cmm_func xor_string(int *result,int *str1,int *str2,int lg);

cmm_func not_string(int *result,int *str1,int lg);

cmm_func neg_string(int *result,int *str1,int lg);

cmm_func copy_string(int *output,int *input,int lg);

cmm_func rshift_string(int *output,int *input,int rshift,int lg);

#ifdef _CMM

cmm_func strcpy(char *outstring,char *instring); cmm_func strlen(char *instring);

cmm_func calloc(int nitems,int size); cmm_func malloc(int size); cmm_func free(int *ptr);

#endif

cmm_func test_string(int *string1,int *string2,int lg,int oper);

cmm_func xfer_const(int *out,int *cst_addr,int lg);

cmm_func xfer_single(int *out,int *cst_addr);

/********************************/

Note the requirement that C± ± function declarations (including main, of course) be preceded by the keyword cmm_func. Also note the conditional assembly portion, used for compatibility with Borland C.

Major Differences between C and C± ±

Although we have tried to keep the differences between regular C and C± ± to a minimum, there are still a few that require some explanations.
