Description

The C library function size_t strxfrm(char *dest, const char *src, size_t n) transforms the first n characters of the string src into current locale and place them in the string dest.

Declaration

Following is the declaration for strxfrm() function.

size_t strxfrm(char *dest, const char *src, size_t n)

Parameters

• dest − This is the pointer to the destination array where the content is to be copied. It can be a null pointer if the argument for n is zero.

• src − This is the C string to be transformed into current locale.

• n − The maximum number of characters to be copied to str1.

Example

The following example shows the usage of strxfrm() function.

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

int main () {
   char dest[20];
   char src[20];
   int len;

   strcpy(src, "Tutorials Point");
   len = strxfrm(dest, src, 20);

   printf("Length of string |%s| is: |%d|", dest, len);
   
   return(0);
}

Let us compile and run the above program that will produce the following result −

Length of string |Tutorials Point| is: |15|
