putc, fputc - write a character to a fortran logical unit
integer function putc (char)
integer function fputc (lunit, char)
These funtions write a character to the file associated with a fortran logical unit bypassing normal fortran I/O. Putc writes to logical
unit 6, normally connected to the control terminal output.
The value of each function will be zero unless some error occurred; a system error code otherwise. See perror(3F).

putc, putchar, fputc, putw - put character or word on a stream
int putc(int c, FILE *stream)
int putchar(int c)
int fputc(int c, FILE *stream)
int putw(int w, FILE *stream)
Putc appends the character c to the named output stream. It returns the character written.
Putchar(c) is defined as putc(c, stdout).
Fputc behaves like putc, but is a genuine function rather than a macro.
Putw appends word (that is, int) w to the output stream. It returns the word written. Putw neither assumes nor causes special alignment
in the file.
SEE ALSO fopen(3), fclose(3), getc(3), puts(3), printf(3), fread(3).
These functions return the constant EOF upon error. Since this is a good integer, ferror(3) should be used to detect putw errors.
Because it is implemented as a macro, putc treats a stream argument with side effects improperly. In particular `putc(c, *f++);' doesn't
Errors can occur long after the call to putc.
