    14 * Description:

    15 * FUNCTION

    16 * <<asctime>>---format time as string

    17 * INDEX

    18 * asctime

    19 * INDEX

    20 * _asctime_r

    21 * ANSI_SYNOPSIS

    22 * #include <time.h>

    23 * char *asctime(const struct tm *<[clock]>);

    24 * char *asctime_r(const struct tm *<[clock]>, char *<[buf]>);

    25 * TRAD_SYNOPSIS

    26 * #include <time.h>

    27 * char *asctime(<[clock]>)

    28 * struct tm *<[clock]>;

    29 * char *asctime_r(<[clock]>)

    30 * struct tm *<[clock]>;

    31 * char *<[buf]>;

    32 * Format the time value at <[clock]> into a string of the form

    33 * . Wed Jun 15 11:38:07 1988\n\0

    34 * The string is generated in a static buffer; each call to <<asctime>>

    35 * overwrites the string generated by previous calls.

    36 * RETURNS

    37 * A pointer to the string containing a formatted timestamp.

    38 * PORTABILITY

    39 * ANSI C requires <<asctime>>.

    40 * <<asctime>> requires no supporting OS subroutines.

    41 *
