.SH NAME
libnvmf_exclusion_write \- atomically replace a list's contents.
.SH SYNOPSIS
.B "int" libnvmf_exclusion_write
.BI "(struct libnvme_global_ctx *ctx "  ","
.BI "const char *name "  ","
.BI "const char *text "  ","
.BI "uint64_t version "  ");"
.SH ARGUMENTS
.IP "ctx" 12
libnvme global context; must not be NULL
.IP "name" 12
list name
.IP "text" 12
full replacement contents (every "exclusion = ..." line is
validated and must sit inside the [exclusions] section;
invalid entries cause -EINVAL and no write)
.IP "version" 12
token from a prior \fBlibnvmf_exclusion_read\fP.  The write proceeds
only if the on-disk list still matches \fIversion\fP; otherwise it
returns -ESTALE and leaves the file untouched, so a concurrent
editor's changes are never silently overwritten.
.SH "DESCRIPTION"
The replacement is installed atomically (temp file + rename) with mode 0644.
.SH "RETURN"
0 on success, -ESTALE if the list changed since \fIversion\fP was read,
-EINVAL for an invalid entry or name, negative errno otherwise.
