sl@0: * INDEX
sl@0: * strpbrk
sl@0: * ANSI_SYNOPSIS
sl@0: * #include <string.h>
sl@0: * char *strpbrk(const char *<[s1]>, const char *<[s2]>);
sl@0: * TRAD_SYNOPSIS
sl@0: * #include <string.h>
sl@0: * char *strpbrk(<[s1]>, <[s2]>)
sl@0: * char *<[s1]>;

sl@0: * <[s2]> (excluding the terminating null character).
sl@0: * RETURNS
sl@0: * <<strpbrk>> returns a pointer to the character found in <[s1]>, or a
