C Runtime Library Reference
Collapse All

RAD Studio has several hundred functions, macros, and classes that you call from within your C and C++ programs to perform a wide variety of tasks, including low- and high-level I/O, string and file manipulation, memory allocation, process control, data conversion, mathematical calculations, and more.

Note: In the online help, each function, macro, and class in the C Runtime Library is listed only once . However, some functions, macros, and classes are defined in more than one header file.

For example, _strerror is defined in both string.h and stdio.h. For functions that are defined in several header files, the online help assigns the function to the first header file in alphabetic order. Thus, you will find _strerror listed in the help in stdio.h but not in string.h.

To find a function, macro, or class that is not listed in a header file in which you expect it, please use the help Index.
