-FUNCTION
- <<memchr>>---find character in memory
-
-INDEX
- memchr
-
-ANSI_SYNOPSIS
- #include <string.h>
- void *memchr(const void *<[src]>, int <[c]>, size_t <[length]>);
-
-TRAD_SYNOPSIS
- #include <string.h>
- void *memchr(<[src]>, <[c]>, <[length]>)
- void *<[src]>;
- void *<[c]>;
- size_t <[length]>;
-
-DESCRIPTION
- This function searches memory starting at <<*<[src]>>> for the
- character <[c]>. The search only ends with the first
- occurrence of <[c]>, or after <[length]> characters; in
- particular, <<NULL>> does not terminate the search.
-
-RETURNS
- If the character <[c]> is found within <[length]> characters
- of <<*<[src]>>>, a pointer to the character is returned. If
- <[c]> is not found, then <<NULL>> is returned.
-
-PORTABILITY
-<<memchr>> requires no supporting OS subroutines.
