getc

Item Value Header file stdio.h Declaration int getc(FILE *stream); Function reads a character from stream. Return returns EOF on file end or error.

When working with binary files, you must use ferror() to check errors.

The functions getc() and fgetc() are identical except that in most implementations getc() is defined as a macro.
