The IC function (and IC_F) will return a tuple with all its input arguments. Except when called with exactly one argument, when then it will return the argument itself.This is done this way so that you can use IC to inspect a function argument at calling point, with no further code ...
Yet other options control the assembler and linker; most of these are not documented here, since you rarely need to use any of them. Most of the command-line options that you can use with GCC are useful for C programs; when an option is only useful with another language (usually C++),...

A pointer to function can be initialized with an address of a function. Because of thefunction-to-pointerconversion, the address-of operator is optional: voidf(int);void(*pf1)(int)=&f;void(*pf2)(int)=f;// same as &f Unlike functions, pointers to functions are objects and thus can ...
Used when certain messages should be displayed but should not cause a non-zero exitcode. --file-list=<file> Specify the files to check in a text file. Add one filename per line. When file is '-,' the file list will be read from standard input. ...
12.3 Things to remember when using new in constructors ) If you use new in constructors, use delete in destructor. Their use should be compatible, pai
A parallel string array to the pointer array contains the "names" of the tables. Queries are extremely simple: just indicate a table number (a zero-based index to the array of table pointers) and the row number (a zero-based index into the nth string array). Thus, the Read function ...
After determining the type of each parameter, any parameter of type “array of T” or of function type T is adjusted to be “pointer to T”. After producing the list of parameter types, any top-level cv-qualifiers modifying a parameter type are deleted when forming the function type. ...
