.TH fmt_pad 3
|
|
.SH NAME
|
|
fmt_pad \- pad a string with spaces.
|
|
.SH SYNTAX
|
|
.B #include <fmt.h>
|
|
|
|
size_t \fBfmt_pad\fP(char *\fIdest\fR, const char *\fIsource\fR,
|
|
size_t \fIsrclen\fR, size_t \fIpadlen\fR,
|
|
size_t \fImaxlen\fR);
|
|
.SH DESCRIPTION
|
|
fmt_pad writes \fIpadlen\fR-\fIsrclen\fR spaces (if that number is
|
|
positive) and then \fIsrclen\fR characters from \fIsource\fR. It
|
|
truncates the output only if the length would exceed \fImaxlen\fR.
|
|
|
|
It returns the number of bytes it wrote.
|
|
|
|
fmt_pad does not append \\0.
|
|
|
|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_pad returns the number
|
|
of bytes it would have written.
