Consider the code below, where I'm converting from string of text to a
string of the (hex) ascii values of the text.
E.G. "sausages" -> "7361757361676573"

Where should I free the memory for char string ascii in convert2ascii()?
Or is there a better algorithm for going about this? (maybe pass a
pointer to a string containing the result as an argument of the function?)

Thanks,

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

int main(void)
{
        char *result;
        char *convert2ascii(char *);

        result = convert2ascii("sausages");
        printf("Res: %s",result);
        return(0);
}

char *convert2ascii(char *txt)
{
         char tmp[3];
         char *ascii;
 

         if((ascii = malloc((strlen(txt)*2)+1)) == NULL)
         {
                 perror("Malloc PWD");
                 exit(EXIT_FAILURE);
         }
 

         do
         {
                 sprintf(tmp,"%x",*txt++);
                 strcat(ascii,tmp);
         } while(*txt);
 
 
 

         return(ascii);
}
