+FUNCTION
+ <<strchrnul>>---search for character in string
+
+INDEX
+ strchrnul
+
+ANSI_SYNOPSIS
+ #include <string.h>
+ char * strchrnul(const char *<[string]>, int <[c]>);
+
+TRAD_SYNOPSIS
+ #include <string.h>
+ char * strchrnul(<[string]>, <[c]>);
+ const char *<[string]>;
+ int <[c]>;
+
+DESCRIPTION
+ This function finds the first occurence of <[c]> (converted to
+ a char) in the string pointed to by <[string]> (including the
+ terminating null character).
+
+RETURNS
+ Returns a pointer to the located character, or a pointer
+ to the concluding null byte if <[c]> does not occur in <[string]>.
+
+PORTABILITY
+<<strchrnul>> is a GNU extension.
+
+<<strchrnul>> requires no supporting OS subroutines. It uses
+strchr() and strlen() from elsewhere in this library.
