.TH fmt_fill 3 |
|
.SH NAME |
|
fmt_fill \- append spaces to a string |
|
.SH SYNTAX |
|
.B #include <fmt.h> |
|
|
|
unsigned int \fBfmt_fill\fP(char *\fIdest\fR, |
|
unsigned int \fIsrclen\fR, unsigned int \fIpadlen\fR, |
|
unsigned int \fImaxlen\fR); |
|
.SH DESCRIPTION |
|
fmt_fill appends \fIpadlen\fR-\fIsrclen\fR spaces (if that number is |
|
positive) to \fIdest\fR (which holds \fIsrclen\fR bytes). It truncates |
|
the output only if the length would exceed \fImaxlen\fR. |
|
|
|
It returns the number of bytes it wrote. |
|
|
|
fmt_fill does not append \\0. |
|
|
|
If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_fill returns the number |
|
of bytes it would have written. |
|
