free( )
Syntax:
undefined
Sends each character in the string out the RS232 pin using putc(). After the string
is sent a CARRIAGE-RETURN (13) and LINE-FEED (10) are sent. In general
printf() is more useful than puts().
If fputs() is used then the specified stream is used where puts() defaults to
STDOUT (the last USE RS232)
All devices
#USE RS232
puts( " ----------- " );
puts( " | HI | " );
puts( " ----------- " );
None
printf(), gets(), RS232 I/O Overview
free( ptr )
Parameters: ptr is a pointer earlier returned by the calloc, malloc or realloc.
Returns:
Function:
No value
The free function causes the space pointed to by the ptr to be deallocated, that is
made available for further allocation. If ptr is a null pointer, no action occurs. If the
ptr does not match a pointer earlier returned by the calloc, malloc or realloc, or if
the space has been deallocated by a call to free or realloc function, the behavior is
undefined.
