41.Sh NAME
42.Nm strftime
43.Nd format date and time
44.Sh SYNOPSIS
45.Fd #include <time.h>
46.Ft size_t
47.Fn strftime "char *buf" "size_t maxsize" "const char *format" "const struct tm *timeptr"
48.Sh DESCRIPTION
49The
50.Fn strftime
51function formats the information from
52.Fa timeptr
53into the buffer
54.Fa buf
55according to the string pointed to by
56.Fa format .
57.Pp
58The
59.Fa format
60string consists of zero or more conversion specifications and
61ordinary characters.
62All ordinary characters are copied directly into the buffer.
63A conversion specification consists of a percent sign
64.Ql %
65and one other character.
66.Pp
67No more than
68.Fa maxsize
69characters will be placed into the array.
70If the total number of resulting characters, including the terminating
71null character, is not more than
72.Fa maxsize ,
73.Fn strftime
74returns the number of characters in the array, not counting the
75terminating null.
76Otherwise, zero is returned.
77.Pp
78Each conversion specification is replaced by the characters as
79follows which are then copied into the buffer.
80.Bl -tag -width "xxxx"
