cfgetospeed - get output baud rate SYNOPSIS
#include <termios.h> speed_t cfgetospeed(const struct termios *termios_p); DESCRIPTION
The cfgetospeed() function shall extract the output baud rate from the termios structure to which the termios_p argument points. This function shall return exactly the value in the termios data structure, without interpretation. RETURN VALUE
Upon successful completion, cfgetospeed() shall return a value of type speed_t representing the output baud rate. ERRORS
No errors are defined. The following sections are informative. EXAMPLES
None. APPLICATION USAGE
None. RATIONALE
Refer to cfgetispeed(). FUTURE DIRECTIONS

cfsetospeed - set output baud rate SYNOPSIS
#include <termios.h> int cfsetospeed(struct termios *termios_p, speed_t speed); DESCRIPTION
The cfsetospeed() function shall set the output baud rate stored in the structure pointed to by termios_p to speed. There shall be no effect on the baud rates set in the hardware until a subsequent successful call to tcsetattr() with the same termios structure. Similarly, errors resulting from attempts to set baud rates not supported by the terminal device need not be detected until the tcsetattr() function is called. RETURN VALUE
Upon successful completion, cfsetospeed() shall return 0; otherwise, it shall return -1 and errno may be set to indicate the error. ERRORS
The cfsetospeed() function may fail if: EINVAL The speed value is not a valid baud rate. EINVAL The value of speed is outside the range of possible speed values as specified in <termios.h>. The following sections are informative. EXAMPLES
