This library also has additional functions inspired from the successful Turbo Pascal one.Ĭompilers that target non-DOS operating systems, such as Linux or OS/2, provide similar solutions the unix-related curses library is very common here. The library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt calls. As originally implemented in Lattice C, the various functions mapped directly to the first few DOS INT 21H functions. The library functions declared by conio.h vary somewhat from compiler to compiler. Some embedded systems or cc65 use a conio-compatible library.
Most C compilers that target UNIX and Linux do not have this header and do not supply the library functions.
Most C compilers that target DOS, Windows 3.x, Phar Lap, DOSX, OS/2, or Win32 have this header and supply the associated library functions in the default C library. This header declares several useful library functions for performing "istream input and output" from a program. It is not part of the C standard library or ISO C, nor is it defined by POSIX. For the profanity, see coño on Wiktionary.Ĭonio.h is a C header file used mostly by MS-DOS compilers to provide console input/output.
