=============== StdIO Functions =============== .. include:: check.rst --------------- Source location --------------- - The main source for string functions is located at: ``libc/src/stdio`` with subdirectories for internal implementations. --------------------- Implementation Status --------------------- Formatted Input/Output Functions ================================ These functions take in format strings and arguments of various types and convert either to or from those arguments. These functions are the current focus (owner: michaelrj). ============= ========= Function Name Available ============= ========= \*printf Mostly \*scanf |check| ============= ========= ``FILE`` Access =============== These functions are used to interact with the ``FILE`` object type, which is an I/O stream, often used to represent a file on the host's hard drive. Currently the ``FILE`` object is only available on linux. ============= ========= Function Name Available ============= ========= fopen |check| freopen fclose |check| fflush |check| setbuf |check| setvbuf |check| ftell |check| fgetpos fseek |check| fsetpos rewind tmpfile clearerr |check| feof |check| ferror |check| flockfile |check| funlockfile |check| ============= ========= Operations on system files ========================== These functions operate on files on the host's system, without using the ``FILE`` object type. They only take the name of the file being operated on. ============= ========= Function_Name Available ============= ========= remove |check| rename |check| tmpnam ============= ========= Unformatted ``FILE`` Input/Output Functions =========================================== The ``gets`` function was removed in C11 for having no bounds checking and therefor being impossible to use safely. ============= ========= Function Name Available ============= ========= (f)getc |check| fgets |check| getchar |check| fread |check| (f)putc |check| (f)puts |check| putchar |check| fwrite |check| ungetc |check| ============= =========
