Category

Prototype

void *memccpy(void *dest, const void *src, int c, size_t n);

Description

Copies a block of n bytes.

memccpy is available on UNIX System V systems.

memccpy copies a block of n bytes from src to dest. The copying stops as soon as either of the following occurs:

- The character c is first copied into dest.
- n bytes have been copied into dest.

Return Value

memccpy returns a pointer to the byte in dest immediately following c, if c was copied; otherwise, memccpy returns NULL.

Example

Copy Code

    #include <string.h>
    #include <stdio.h>
    int main(void)
    {
       char *src = "This is the source string";
       char dest[50];
       char *ptr;
       ptr = (char *) memccpy(dest, src, 'c', strlen(src));
       if (ptr)
       {
          *ptr = '\0';
          printf("The character was found: %s\n", dest);
       }
       else
          printf("The character wasn't found\n");
       return 0;
    }
