  char c,                /* byte to find */
  unsigned int len);     /* maximum buffer length */

The fmemchr function scans buf for the character c in the first len bytes of the buffer.

Note

• This function uses far pointers to objects and may be used in any memory model other than Tiny Model.

The fmemchr function returns a pointer to the character c in buf or a null pointer if the character was not found.
