Whenever using eina we need to include it:
#include <stdio.h> #include <Eina.h>
In our main function we declare(and initialize) some variables and initialize eina:
int main(int argc EINA_UNUSED, char **argv EINA_UNUSED) { char *names = "Calvin;Leoben;D'anna;Simon;Doral;Six;Daniel;Sharon"; char *str; char *tmp; char *prologue; char *part1 = "The Cylons were created by man. They evolved. They rebelled."; char *part2 = "There are many copies. And they have a plan."; char **arr; int i; eina_init();
It's frequently necessary to split a string into its constituent parts, eina_str_split() make's it easy to do so:
arr = eina_str_split(names, ";", 0); for (i = 0; arr[i]; i++) printf("%s\n", arr[i]);
Another common need is to make a string uppercase or lowercase, so let's create a string and make it uppercase and then make it lowercase again:
free(arr[0]); free(arr); str = malloc(sizeof(char) * 4); strcpy(str, "bsd"); eina_str_toupper((char **)&str); printf("%s\n", str); eina_str_tolower(&str); printf("%s\n", str);
Next we use eina to check if our names
string starts or ends with some values:
if (eina_str_has_prefix(names, "Calvin")) printf("Starts with 'Calvin'\n"); if (eina_str_has_suffix(names, "sharon")) printf("Ends with 'sharon'\n"); if (eina_str_has_extension(names, "sharon")) printf("Has extension 'sharon'\n");
When strings will be used in a terminal(or a number of other places) it necessary to escape certain characters that appear in them:
tmp = eina_str_escape("They'll start going ripe on us pretty soon."); printf("%s\n", tmp);
Much as we previously split a string we will now join two strings:
free(tmp); prologue = malloc(sizeof(char) * 106); eina_str_join_len(prologue, 106, ' ', part1, strlen(part1), part2, strlen(part2)); printf("%s\n", prologue);
With strlcpy() we can copy what portion of the prologue
fits in str
and be sure that it's still NULL terminated:
eina_strlcpy(str, prologue, 4); printf("%s\n", str);
Since we are done with prologue
and str
we should free them:
free(prologue); free(str);
Finally we see strlcat in action:
str = malloc(sizeof(char) * 14); sprintf(str, "%s", "cylons+"); eina_strlcat(str, "humans", 14); printf("%s\n", str);
And then shut eina down and exit:
free(str); eina_shutdown(); return 0; }
