Re: [Libvir] PATCH: Implement CDROM media change for QEMU/KVM driver

+ char *cmd; + char *reply; + /* XXX QEMU only supports a single CDROM for now */ + /*cmd = malloc(strlen("change ") + strlen(olddisk->dst) + 1 + strlen(newdisk->src) + 2);*/ + cmd = malloc(strlen("change ") + strlen("cdrom") + 1 + strlen(newdisk->src) + 2); + if (!cmd) { + qemudReportError(dom->conn, dom, NULL, VIR_ERR_NO_MEMORY, "monitor command"); + return -1; + } + strcpy(cmd, "change "); + /* XXX QEMU only supports a single CDROM for now */ + /*strcat(cmd, olddisk->dst);*/ + strcat(cmd, "cdrom"); + strcat(cmd, " "); + strcat(cmd, newdisk->src); + strcat(cmd, "\n"); Much as it irritates me to say it, a fixed-size buffer and snprintf might be preferable here ...
