Descriptions of implementation-defined behavior%p in scanf() (7.9.6.2)The %p conversion specifier, scan pointer, to scanf() reads a hexadecimal number andconverts it into a value with the type void *.Reading ranges in scanf() (7.9.6.2)A - (dash) character is always treated as a range symbol.File position errors (7.9.9.1, 7.9.9.4)On file position errors, the functions fgetpos and ftell store EFPOS in errno.Message generated by perror() (7.9.10.4)The generated message is:usersuppliedprefix:errormessageAllocating zero bytes of memory (7.10.3)The calloc(), malloc(), and realloc() functions accept zero as an argument.Memory will be allocated, a valid pointer to that memory is returned, and the memoryblock can be modified later by realloc.Behavior of abort() (7.10.4.1)The abort() function does not flush stream buffers, and it does not handle files,because this is an unsupported feature.Behavior of exit() (7.10.4.3)The argument passed to the exit function will be the return value returned by the mainfunction to cstartup.Environment (7.10.4.4)The set of available environment names and the method for altering the environment listis described in Environment interaction, page 66.system() (7.10.4.5)How the command processor works depends on how you have implemented the systemfunction.
