/* @deftypefn Supplemental void* memchr (const void *@var{s}, int @var{c}, @ size_t @var{n}) This function searches memory starting at @code{*@var{s}} for the character @var{c}. The search only ends with the first occurrence of @var{c}, or after @var{length} characters; in particular, a null character does not terminate the search. If the character @var{c} is found within @var{length} characters of @code{*@var{s}}, a pointer to the character is returned. If @var{c} is not found, then @code{NULL} is returned. @end deftypefn */ #include <ansidecl.h> #include <stddef.h> PTR memchr (register const PTR src_void, int c, size_t length) { const unsigned char *src = (const unsigned char *)src_void; while (length-- > 0) { if (*src == c) return (PTR)src; src++; } return NULL; }
