beyond the capabilities of the preprocessor. For example, typedef int (*PFI)(char *, char *); creates the type PFI, for ``pointer to function (of two char * arguments) returning int,'' which can be used in contexts like PFI strcmp, numcmp; in the sort program of Chapter 5. Besides...
Currently adding to pointers doesn't work: stdin:1:37-38: ERROR: The + operator can not be used on expressions of types cast, integer BEGIN { $a = (uint16*) 123; $b = $a + 5; } In C adding to a pointer uses the pointee size to increment,...
ISPF provides the binary string data format to support dialog applications written in the C language. When a variable defined as BINSTR is updated in the function pool, ISPF pads with binary zeros. This is desirable within C function programs, because the C language uses binary zeros to mark ...
An example of information that the publisher must define relates to the use of pointers to pass data to functions. A pointer is a location in memory that indicates the start of a block of data. To pass this data to MATLAB safely, the publisher must specify the size of the data. The fu...
