Questions tagged [conio]

A non-standard C library that enables users to move the cursor on Terminals and place characters at certain locations.

The conio library is a C library mostly provided by MS-DOS compilers to provide console input/output beyond what is provided by the C standard library.

Conio does not form part of the C standard library or ISO C, nor is it defined by POSIX. This means that the functions in the conio library vary somewhat between compilers.
