universal write function

Good afternoon everyone :)

I have written two functions to write data to a LCD screen.One writes a character and the other writes a string.

Code:

---

void write(unsigned char z)
{
    enable = 0;
    rs = 1;
    rw = 0;
    delay(9000);
    P10_OUT = z;
    delay(9000);
    enable = 1;
}

void str_write(char *buffer)
{
    int i = 0;
    for(i=0; i<=(strlen(buffer)-1); i++)
    {
        if(i > 19)
            break;
        delay(100000);
        write(buffer[i]);
    }
}

---

Is there any way i can combine them into a single function ,so that i don't have to use 2 separate functions to write a char and string?
Something like:

uni_write('h') ==> should write h.
uni_write(str_Array) ==>should write contents of str_Array.

Thanks in advance :)

If you get the strlen() from the calling function, you could make that a parameter to the one universal write function. Pass that value in along with the pointer to the first char, and have it print it out in a for loop. One char or 150 char's, it will work either way.

Could you please post an example code Adak.
I have got this so far...

Code:

---

char buff[] = "\0";      //in main
char c = '\0';      //in  main
str_write(stringname,c);    //for writing string
str_write(buff,char_name);  //for writing character

//my function
void univ_write(char *buffer,ch)
{
    int i = 0;
    if(ch == '\0')
    {
        __nop();    //no operation
    }
    else
    {
        write(ch);
    }


    if(buffer == "\0")
    {
        __nop();
    }
    else
    {
        for(i=0; i<=(strlen(buffer)-1); i++)
        {
            if(i > 19)
                break;
            delay(100000);
            write(buffer[i]);
        }
    }
}

---

Code:

---

#include <stdio.h>
#include <string.h>

void univ_write(char *buffer, int length);

int main(void) {
 
  int buffLength=0;
  char buff[100] = {"The first time, ever I saw your face"};     
  //just an example. You should get a string from the user -
  //one char or 99 char's.

 
  buffLength=strlen(buff);
  univ_write(buff, buffLength);

  return 0;
}
void univ_write(char *buffer, int length)
{
    int i = 0;
    for(i=0; i<length; i++)
    {
        printf("%c",buffer[i]);
    }
  printf("\n");
}

This is one way, not the only way.
