User Manual

puts

Writes the string pointed to by s to the serial port and appends a new-line character to the

output. The terminating null character is not written.

Synopsis

#include <stdio.h>

int puts(char *s);

Returns

EOF if an error occurs; otherwise, it is a non-negative value.

Example

int i;

char strp[]="COMPASS";

i=puts(str);

The UART must be initialized using the Zilog init_uart() function. See init_uart – see

page 182.

qsort

Sorts an array of nmemb objects, the initial member of which is pointed to by any base.

The size of each object is specified by size.

The array is sorted in ascending order according to a comparison function pointed to by

compar, which is called with two arguments that point to the objects being compared. The

compar function returns an integer less than, equal to, or greater than zero if the first argu-

ment is considered to be respectively less than, equal to, or greater than the second.

If two members in the array compare as equal, their order in the sorted array is unspeci-

fied.

Synopsis

#include <stdlib.h>



void qsort(void *base, size_t nmemb, size_t size, int

(*compar)(const void *, const void *));
