<stdbool.h>(P)						     POSIX Programmer's Manual						    <stdbool.h>(P)

NAME

       stdbool.h - boolean type and values

SYNOPSIS

       #include <stdbool.h>

DESCRIPTION

       The <stdbool.h> header shall define the following macros:

       bool   Expands to _Bool.

       true   Expands to the integer constant 1.

       false  Expands to the integer constant 0.

       __bool_true_false_are_defined

	      Expands to the integer constant 1.

       An application may undefine and then possibly redefine the macros bool, true, and false.

       The following sections are informative.

APPLICATION USAGE

       None.

RATIONALE

       None.

FUTURE DIRECTIONS

       The ability to undefine and redefine the macros bool, true, and false is an obsolescent feature and may be withdrawn in a future version.

SEE ALSO

       None.

NAME

       index - character string operations (LEGACY)

SYNOPSIS

       #include <strings.h>

       char *index(const char *s, int c);

DESCRIPTION

       The index() function shall be equivalent to strchr().

RETURN VALUE

       See strchr() .

ERRORS

       See strchr() .

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       The strchr() function is preferred over this function.

       For maximum portability, it is recommended to replace the function call to index() as follows:

	      #define index(a,b) strchr((a),(b))

RATIONALE

       None.

FUTURE DIRECTIONS

       This function may be withdrawn in a future version.
