getc

Reads a single character from a filehandle.

Returns the next character from the specified filehandle as a one-character string. When called without arguments, reads from STDIN (filehandle id 0). Returns undef at end-of-file or on error.

Accepts both lexical ($fh) and bareword (FH) filehandles.
