getc, fgetc - get a character from a logical unit
integer*4 function getc (char) character char
integer*4 function fgetc (lunit, char) character char
These functions return the next character from a file associated with a FORTRAN logical unit, bypassing normal FORTRAN I/O.
getc reads from logical unit 5, normally connected to the control terminal input.
The value of each function is a system status code. Zero indicates that no error occurred on the read; -1 indicates that the end of the file was detected. A positive value is either a SunOS system error code or an f77 I/O error code. See perror(3F).
Do not mix normal Fortran I/O with calls to getc or fgetc.
