5.14 rawmemchr—find character in memory

Synopsis 

     #include <string.h>
     void *rawmemchr(const void *src, int c);

Description
This function searches memory starting at *src for the character c. The search only ends with the first occurrence of c; in particular, NUL does not terminate the search. No bounds checking is performed, so this function should only be used when it is certain that the character c will be found.
Returns
A pointer to the first occurance of character c.
Portability
rawmemchr is a GNU extension.

rawmemchr requires no supporting OS subroutines.
