|
.Sh SYNOPSIS
|
|
.In stdint.h
|
|
.In tsd/strutil.h
|
|
.Ft size_t
|
|
.Fn tsd_strlcat "char *dst" "const char *src" "size_t size"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm tsd_strlcat
|
|
function appends the NUL-terminated string pointed to by
|
|
.Va src
|
|
to the NUL-terminated string stored in the buffer pointed to by
|
|
.Va dst .
|
|
The
|
|
.Va size
|
|
argument specifies the total size of the buffer including the space
|
|
occupied by the existing string and space for the terminating NUL
|
|
character.
|
|
If the sum of the lengths of both strings exceeds the available space,
|
|
the result is truncated.
|
|
In all cases, the destination buffer is properly NUL-terminated.
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn tsd_strlcat
|
|
function returns the sum of the lengths of the original strings.
|
|
If this number is equal to or greater than the value of the
|
|
.Va size
|
|
argument, the string was too long to fit in the buffer.
|
|
.Sh IMPLEMENTATION NOTES
|
|
If the
|
|
.Dv HAVE_STRLCAT
|
|
preprocessor macro is defined to 0 or undefined, the
|
|
.In tsd/sha1.h
|
|
header provides a
|
|
.Fn strlcat
|
|
macro as an alias to
|
|
.Fn tsd_strlcat .
