.th PUTCHAR
|
|
.sh NAME
|
|
putchar - write a character
|
|
.sh SYNOPSIS
|
|
.ft B
|
|
int getchar(c)
|
|
.br
|
|
char c;
|
|
.ft R
|
|
.sh DESCRIPTION
|
|
Putchar writes one character to the standard output (VERSAdos file #6).
|
|
Putchar assumes it is writting ASCII characters and buffers all
|
|
characters until a '\\n' is received. Then the '\\n' is stripped
|
|
from the buffer and the record is written. Tab characters are left
|
|
as '\\t' -- they are not translated into the VERSAdos convention
|
|
of a negative number. Putchar returns the character received for
|
|
success and returns a negative integer for failure.
|
|
|
|
Putchar may aso be used to write ASCII characters to a file other than
|
|
the standard output. If the external variable named fout is set to
|
|
any valid file descriptor, then putchar writes to that file rather
|
|
than the standard output. The routine named flush which writes
|
|
any characters in the putchar output buffer may be called to
|
|
force a write; however, writes occur automatically at the end
|
|
of each record ('\\n' delimiter).
